The correct answer is d. 9 + 0 = 9
Further explanation:
If x is an element of a set, and adding a number to it doesn't change it i.e. the result is also x then the number is called additive identity.
In mathematics, 0 is considered as additive identity because no matter with which number it is added, the number always remains same.
In the given options:
Option a. 5*1=5 demonstrates multiplicative identity
Option b. 3+5=5+3 demonstrates commutative property
Option c. 4+ (6 + 8) = (4+6) +8 demonstrates associative property
While the last option
d. 9 + 0 = 9 demonstrates additive identity as zero is being added to 9 and the answer is also 9.
The correct answer is d. 9 + 0 = 9
