Answer:
C. Quintic Binomial
Step-by-step explanation:
The polynomial only has 2 terms, 3x^5 and 3,
So that leaves us with A and C.
Since A is a cubic binomial meaning that the exponent must be cubed or more specifically x^3.
That leaves us with C. Quintic Binomial, through this logic you can also say that Quin meaning 5, is correct.
