Answer: option a.

Explanation:

To factor a polynomial of degree 2, with the form
ax^(2)+bx+c, you must find two number whose sum is a and whose product is c. Then:

a)
x^2+3x+2\\(x+1)(x+2)

(it can be factored into two binomials)

b)
x^2+4x+5 cannot be factored into two binomials.

c)
x^2+5x+7 cannot be factored into two binomials.

d)
x^2+6x+10 cannot be factored into two binomials.

Therefore, the answer is the option a.
