The first statement cannot be true because only female animals lay eggs. Because some dogs are cubs and all cubs are animals, we can say some dogs are animals[II is true]. Similarly, it is given that some cubs are dogs, then some must not be dogs[III is true].

 A

true.

 B

false.

 C

uncertain.

II and III only.

There is not enough information to support any of the statements. Raman is known to have a minivan, but it is not known which of his car is blue. There is no way to know if Raman's favorite color is blue.

 B

false.

Because the first two statements are true, Panchkula is west of Mohali and southwest of Chandigarh. Therefore, the third statement is false.
