Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
1400=23527
The number of ways in which 1400 can be expressed as a product of two positive integers is
(3+1)(2+1)(1+1)2=12
Statement 2 is correct but does not explain statement 1 as it just gives the information about the prime factor about which 1400 is divisible.
