Right, the option E should be the answer, else conclusion 1 and 3 are contradictory and there is no option for neither nor.

Statement III is right;.
Fact 1: All drink mixes = beverages;.
Fact 2: All beverages = drinkable.
According to this, all drink mixes = drinkable ===> regardless of the color. Therefore statement III (All red drink mixes are drinkable) is right.
Fact 1: All drink mixes = beverages;.
Fact 2: All beverages = drinkable.
According to this, all drink mixes = drinkable ===> regardless of the color. Therefore statement III (All red drink mixes are drinkable) is right.

The I and III statement should be the answer. Since all red drink mixes are drinkable so it could also fair to say that some drink mixes are red (and drinkable) which all refer all to beverages. I stand to be corrected>.

"All drink mixes are beverages" but not all beverages are drink mixes so we can conclude "some beverages are drink mixes" and "Some beverages are red".
I. Some drink mixes are red. - Only in extreme case it is true.
II. All beverages are drink mixes - Is false as per above discussion.
"All drink mixes are beverages" and "All beverages are drinkable". So we can say "All drink mixes are drinkable".
III. All red drink mixes are drinkable - true as cumulative result.
So Option D) III Only is the correct answer.

The 1st one is wrong because some beverages which are not drink mixes can be red. The second one is obvious.
Hence the third.
Hence the third.

Here it is given that in fact 1 "all drink mixes are beverages", it does not mean that all the beverages will only be drink mixes, there might be some beverages which are not drink mixes. Hence Statement II is false.
In Fact 3 it is given that "some beverages are red", it does not mean that those beverages would be only drink mixes, it may or may not be. Hence it is uncertain. So Statement I is false.
In Fact 2 it is given that "all beverages are drinkable", it means all drink mixes which were beverages and beverages which wee red and beverages themselves it means everything is drinkable. Hence Statement III is true which means all drink mixes which may be red are drinkable. Hence only Statement III is true. It would be easily understood when we use Venn diagrams.
In Fact 3 it is given that "some beverages are red", it does not mean that those beverages would be only drink mixes, it may or may not be. Hence it is uncertain. So Statement I is false.
In Fact 2 it is given that "all beverages are drinkable", it means all drink mixes which were beverages and beverages which wee red and beverages themselves it means everything is drinkable. Hence Statement III is true which means all drink mixes which may be red are drinkable. Hence only Statement III is true. It would be easily understood when we use Venn diagrams.
