Two statements are given followed by two conclusions numbered I and II. Assuming the statements to be true, even if they seem to be at variance with commonly known
facts, decide which of the conclusions logically follow(s) from the statements.
Statements:
I. No letter is an alphabet.
II. All alphabets are words.
Conclusions:
I. All words can never be letters.
II. All letters being words is a possibility.

​Statements:
I. No letter is an alphabet.
II. All alphabets are words.

​Conclusions:

I. All words can never be letters. (Follows, Since all alphabets are words (statement 2) and no letter is an alphabet (statement 1), this implies that words (which are alphabets) cannot be letters.)
II. All letters being words is a possibility. (Follows, Since no letter is an alphabet and all alphabets are words, there is a possibility that letters could be words, but it does not have to be the case.)

Thus, correct option is (d).
