The first statement is negative and the other statement is positive and marge and the negative conclusion must be followed & positive conclusion can't be followed ever for this statement.
No, the door is Cat true and we can also read from the back.
No Cat is door because in the negative statement no is hidden so statement 1st and 2nd both are followed.

Option 1 . Not correct because in 2nd statement cats is undistributed according to rule as in universal negative (E) statement both subject and predicate is distributed so this is wrong more over E+A =O* (reverse).
Option 2. Again E+A=O* (reverse) fallacy or mistake as you understand and distribution fallacy is also here.
Option 3 is correct According to conversion rule A changes only in I here subject and predicate interchange their position.
Option 4. The answer can never be positive if any statement is negative so this is also wrong.
Option 2. Again E+A=O* (reverse) fallacy or mistake as you understand and distribution fallacy is also here.
