$2x + 7$
a) linear polynomial
b) linear binomial
c) quadratic binomial
d) linear trinomial
e) cubic trinomial
f) cubic binomial

Explanation:

Step1: Count number of terms

The expression $2x + 7$ has two terms: $2x$ and $7$.

Step2: Find the degree

The highest exponent of $x$ is 1, so degree is 1 (linear).

Step3: Name the polynomial

Two terms = binomial; degree 1 = linear. So it's a linear binomial.

Answer:

B) Linear binomial
