\(m\) & \(n\) are prime.
So their lcm will be the multiplication of both the numbers. \(mn\)

Given that m and n are two different prime numbers and we need to find the LCM of m and n
Theory: LCM of two co-prime numbers = Product of the numbers.
(Co-prime numbers are the numbers are prime relative to each other => They don't have any common factor apart from 1)
Given that m and n are different prime numbers => m and n are co-prime
=> they will have only one common factor 1
=> LCM(m,n) = m*n = mn
Example: LCM(2,3) = 2*3 = 6
LCM(3,5) = 3*5 = 15
So, Answer will be A
Hope it helps!
