Answer:
Option 1 is correct.
Explanation:
Given the following statements we have to choose the true statement.
First option: All constants are of degree 0
The constant term of a polynomial is the term in which the variable does not appear i.e no variable include in that term i.e of degree 0.
Second option: All monomials are of degree 1
Monomials are the polynomials containing 1 term not necessarily of degree 1. Hence, the above statement not true.
Third option: All binomials are of degree 1
Binomials are the polynomials containing 2 term not necessarily of degree 1. Hence, the above statement not true.
Fourth option: All trinomials are of degree 3
Trinomials are the polynomials containing 3 terms not necessarily of degree 3. Hence, the above statement not true.
Hence, option 1 is correct.
