The parameter on which the value of the determinant |{:(1,,a,,a^(2)),(cos (p-d)x ,,cos px,,cos(p+d)x),(sin (p-d)x,,sin px,,sin (p+d)x):}|` does not depend is `a` b. `p` c. `d` d. `x`

Explanation

To solve the given determinant and find the parameter on which its value does not depend, we will follow these steps:

### Step 1: Write the Determinant
We start with the determinant:

\[
D = \begin{vmatrix}
1 & a & a^2 \\
