(1) Set A consists of 4 numbers.
(2) Set B consists of 5 numbers.



set A is a subset of B

1 and 2 are not individually sufficient to solve the question

combining

a has 4 numbers
b has 5 numbers

a= (1,2,3,4) / (1,3,4,5) range = 3/4
b= ( 1,2,3,4,5) range = 4

range can be less or equal

(E) imo

Number of terms does not helpful In calculating range

Because main thing matters is what numbers constitute set not number of terms.

So answer E
