regarding the sum below?

A. The sum is a polynomial.

B. The sum is an integer.

C. The sum is a rational number.

D. The sum is a rational expression.

Answer 1

Answer:

D. The sum is a rational expression.

Step-by-step explanation:

the given expression is  a/b +c/d

so in the question it is given that b and d are non zero values

a/b is rational number and c/d is a rational number

so if both are rational number , so we know that the sum of rational number is also a rational number.

The right option is D. The sum is a rational expression
