Read the given two statements and decide which of the conclusions given in the options follows from the statements.

Statements:

1. All men are mortal.

2. Philip is a man.

Option (a): Philip is not a man. (False)

This contradicts Statement 2, which clearly states that Philip is a man.

Option (b): Philip must be mortal. (True)​

Since all men are mortal (Statement 1), and Philip is a man (Statement 2), it logically follows that Philip must be mortal.

Option (c): All mortals are men. (False)​

Statement 1 only states that all men are mortal, but it does not say that all mortals are men. There could be other mortals who are not men.

Option (d): Philip is not mortal. (False)​

This contradicts the logical conclusion from the statements.

Thus, correct option is (b).
