Since there are 400 lines per page, and page frame number 11 is the last one in page 3, the next page will start at frame number 12, which is equivalent to line 4800. Therefore, line 433 is in page frame number 11 + 433/400 = 12.0825. However, we round down to the nearest integer, which gives us page frame number 12. Hence, the actual memory location for line 433 is 12 * 400 + (433 mod 400) = 4,833. But since the options are not in hexadecimal, we choose the closest approximation, which is D) 4033.
