Option a:
Option b:
Option c:
Explanation:
The highest degree of a polynomial is the largest exponent of that variable.
Now, we shall determine the polynomial with degree 3.
Option a:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option a is the correct answer.
Option b:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option b is the correct answer.
Option c:
From the expression , the highest degree of the polynomial is 3.
Hence, is a polynomial with a degree of 3.
Hence, Option c is the correct answer.
Option d:
From the expression , the highest degree of the polynomial is 1.
Hence, is a polynomial with degree 1.
Hence, Option d is not the correct answer.
