A probability question with sequences

A sequence of numbers X1, X2,... are produced by taking a random number from the set {1,2,3...n}.

The summation Sk is defined to be X1+X2+...+Xk.

Which of the following is a correct expression for the probability that Sk can be smaller or equal to n?

Why? Explain

Thank you in advance! My teacher gave this to me for math extension 1 & I’m so confused, I don’t even know where to begin with this question!
