A point source of light is taken away from the experimental setup of photoelectric effect, then which is the most appropriate statement?

Question

$\begin{array}{1 1} \text{(a) Saturation photocurrent remains same, while stopping potential increases.} \\ \text{(b) Saturation photocurrent and stopping potential both decrease.} \\ \text{(c) Saturation photocurrent decreases while stopping potential remains same.}\\ \text{(d) Saturation photocurrent decreases and stopping potential increases.} \end{array}$
