Since s is proportional to t, we can set up the proportion s/t = k, where k is the constant of proportionality. Solving for k, we get k = s/t. Using the given values, we can solve for k: k = 50/150 = 1/3. Now we can use k to find t when s = 75: 75/t = 1/3. Solving for t, we get t = 225. Therefore, the answer is Choice C.
