Options

• 1, 2 and 3

• 1 and 2

• 3 and 2

• 1, 2, 3 and 4

Answer 1

1 and 2

Explanation:

(1)

Clearly, some bikes are scooters.
(2)

Clearly, no children are red.
(3)

From the above figure, we cannot conclude that some pencils are markers.

(4)

Every man has a wife and all wives are devoted. So, we can clearly say that some devoted have a husband. Hence, no devoted has husband does not logically follow.
