explain your reasoning for your choice(s).

a b and c

Step-by-step explanation:

a) a number is divisible by 3 if the sum of its dígits is divisible by 3:

3+4+5+1+5=18

18 is divisible by 3 (6*3=18), then 34515 is divisible by 3 too.

b)a number is divisible by 9 if the sum of its dígits is divisible by 9:

3+4+5+1+5=18

18 is divisible by 9 (9*2=18), then 34515 is divisible by 9 too.

c) a number is divisible by 5 if its last digit is 5 or 0

then, 34515 is divisible by 5
