Answer:

A. The sum is a rational expression

Step-by-step explanation:

we are given

2/a+ c/d

we are given that

'b' and 'd' are non-zero values

So,

a/b is a rational number

c/d is a rational number

we can see that both are added

So, sum of rational expression is also a rational expression

so...

A. The sum is a rational expression
