3/5 for flaky
9/5 for elongated
So, 3 * 3/5 = 9/5.

So, the answer will be C.

Any aggregate is said to be elongated if its length is more than 1.8 * mean dimension hence the correct answer is B only. It does not matter whether it is flaky or whatever and the answer would have been 3*least dimension if the length is asked compared to the least dimension i.e. thickness in the flaky aggregate.

First of all. It's either 2 nor 3.

Flakiness and Elongation are not released to one other. Flakiness depends on the width of the aggregate and Elongation on length.

For Elongation, the length should be more than 1.8x of the mean size.
So exact the answer is 1.8,
1.8<2.

So, the nearest answer is 2.
Thank you.
