Answer:

The correct option is c.

Step-by-step explanation:

Option a,

8x^2-10x-3

8x^2-12x+2x-3

4x(2x-3)+(2x-3)

(2x-3)(4x+1)

A prime polynomial cannot be written as a product of lower-degree polynomials. Therefore option a is not prime.

Similarly find the factors of other expressions.

8x^2+2x-3

8x^2-6x+4x-3

2x(4x-3)+(4x-3)

(2x+1)(4x-3)

Therefore option b is not prime.

8x^2-6x-3

This polynomial factored further and cannot be written as a product of lower-degree polynomials.  Therefore it is prime and option c is correct.

8x^2+23x-3

8x^2+24x-x-3

8x(x+3)-(x+3)

(8x-1)(x+3)

Therefore option d is not prime.
