Best answer
Right choice is (c) 40 pin with DIP

For explanation I would say: The 8051 family members have different packages, such as DIP(Dual In Line), QFP(Quad Flap Package), LLC(Leadless Chip Carrier) they all have 40 pins that are dedicated to different functions. Especially 8051 have a Dual in Line package.
