Help me solve this 

**Problem Statement:**

Find the second derivative of the function:

\[
s = \frac{t^9 + 10t + 7}{t^2}
\]

**Options:**

- **A.** \(\frac{d^2s}{dt^2} = 7t^5 - \frac{10}{t^3} - \frac{14}{t^4}\)

- **B.** \(\frac{d^2s}{dt^2} = 42t^7 + \frac{20}{t} + \frac{42}{t^2}\)

- **C.** \(\frac{d^2s}{dt^2} = 7t^6 - \frac{10}{t^2} - \frac{14}{t^3}\)

- **D.** \(\frac{d^2s}{dt^2} = 42t^5 + \frac{20}{t^3} + \frac{42}{t^4}\)

**Explanation:**

This mathematical problem involves finding the second derivative of a given function. The function \(s\) is presented in a rational form, where the numerator is a polynomial \(t^9 + 10t + 7\) and the denominator is \(t^2\).

Candidates need to differentiate this function twice with respect to \(t\) to determine which option (A, B, C, or D) correctly represents the second derivative.
