A different way to solve this is to go sentence by sentence and decide which word fits each one, then count how many times each word appears in that final list.
Now count the words in this list: arise appears once, rise appears once, and arose appears twice, in sentences (ii) and (iv). Raise does not appear at all, since it always needs a direct object.
Let's summarize:
So the maximum number of times any single word fits is 2, confirming option (3).
