Question

The multiplicative identity for integers is?

• A. 0
• B. -1
• C. 1
• D. None of these

Answer 1

The correct option is C

1

The multiplicative identity of any integer p is a number q which when multiplied with p, leaves it unchanged, i.e. q is called the multiplicative identity of any integer p, if p × q = p.

Now, when we multiply 1 with an integer p we get:
p × 1 = p = 1 × p

So, 1 is the multiplicative identity for integers.
