Explanation:

(60 x 62 x 64 x 66)/7 , The number 63 when divided by 7 will give remainder 0 ,
when number 62 divided by 7 it gives remainder 6 or -1
similarly we can write remainder by 60 = -3 , 62=-1 , 64 = 1 , 66 = 3
so when we divide the multiplication of all remainders with 7 we will get the remainder as 2,
so the right answer for the question is option (d)
