a. $4x^3 + 2x$
b. $x^2 + 5x + 7$
c. $3x^4 - 5x^2 + x + 8$
d. $6x^2 - 2$

Explanation:

Step1: Count terms for option a

$4x^3$ and $2x$: 2 terms

Step2: Count terms for option b

$x^2$, $5x$, and $7$: 3 terms

Step3: Count terms for option c

$3x^4$, $-5x^2$, $x$, and $8$: 4 terms

Step4: Count terms for option d

$6x^2$ and $-2$: 2 terms

Answer:

b. $x^{2}+5x+7$
