The degree of a polynomial is the highest exponent in the polynomial. In this case, the polynomial 2x^3+7x^2+x+1 has a highest exponent of 3, so the degree is 3. The other options, 2, 3, and 6, do not represent the degree of the polynomial as they are either lower or higher exponents than the highest exponent in the polynomial. Therefore, they are incorrect.
