2520 is correct answer because all numbers from1-10

Divisibility rules of numbers from 1 to 10
1- all numbers are divisibile
2-if last digit is even then divisibile
3- sum of the digits is multiple of 3 then divisibile
4-last two digits must be divisibile by 4
5- last digit must be 0 or 5
6- the digit must be divisibile by both 2 and 3
7-the last digit should be doubled and substracted by rest of the digit and the answer must be divisibile by 7
8-last 3 digits of the number should be divisibile by 8
9 -sum of number should be multiple of 9
10 - last digit must be zero

a) 10 is not divisibile by 3
b)100 not divisibile by 3
c)504 not divisibile by 5
d) divisibile by all

so option d is correct answer

We need to find the LCM of 1, 2, 3, 4, 5, 6, 7, 8, 9,10
the LCM is 2520
