Solution

The correct option is A $7$
The degree is the highest power of an exponent in the polynomial.
In the given polynomial,
$(6 x^{7} - 7 x^{3} + 3 x^{2} + 2 x - 1)$

It can be clearly observed that the first term $6 x^{7}$ has the highest power of $x$ i.e $7$ .

Thus, the degree of the given polynomial is $7$ .

Hence, $7$ is the correct answer.
