a.1
b.2
c.4
d.5

C.4

Step-by-step explanation:

We are given that five rational numbers

We are given that  product of five rational numbers is positive.

We have to find what is the maximum number of rational number can be negative.

We know that when we multiply 2,4,6,8, negative number then the product will be positive.

If we multiply two rational number then the product will be positive and when we multiply 4 negative rational number then the product will be positive.

Hence, the maximum number of rational number that can be negative is 4.

C.4
