IMO E is the option.
Total number of factors = 16 As 210 = 2*3*5*7
The number that will be multiple of 6 must have 2*3 as a factor in it. There are 4 possible numbers of such type i.e. 2*3, 2*3*5, 2*3*7, 2*3*5*7.
Probability = 4/16 = 1/4.

210= 2*3*5*7
Total number of factors= 2*2*2*2=16
Factors that are divisible by 6 can be written as \(2*3*5^a*7^b\)
a and b can take 2 values (0 or 1)
Total number of factors that are divisible by 6= 2*2=4
Probability= 4/16=1/4
