Answer:

Among the given options option (a) 2 is correct.

Step-by-step explanation:

Given :  

Least prime factor of ‘a’ is 3 and least prime factor of ‘b’ is 7.

sum of least prime factors of a and b = (a + b) = 3 + 7 = 10

(a + b) = 10

Least factor of 10 is 2

Hence, the least factor of (a + b) is also 2.
