To determine if a number is a multiple of 8, we need to check if it is divisible by 8 without leaving a remainder.
Let's go through the options:
a) 2: 2 is not divisible by 8 because 8 divided by 2 is 4 with a remainder of 0.
b) 4: 4 is not divisible by 8 because 8 divided by 4 is 2 with a remainder of 0.
c) 12: 12 is not divisible by 8 because 8 divided by 12 is 1 with a remainder of 4.
d) 16: 16 is divisible by 8 because 8 divided by 16 is 2 with a remainder of 0.
Therefore, the number that is a multiple of 8 from the given options is d) 16.
