Aprogram needs to simulate 15 trials. during each trial, a game spinner with four possible options is spun 50 times. which loop structure best represents the code needed to accomplish this task? for(int s = 0; s < 50; s++) for(int t = 0; t < 15; t++) for(int s = 1; s < 50; s++) for(int t = 1; t < 15; t++) for(int t = 0; t < 15; t++) for(int s = t; s < 50; s++) for(int t = 0; t < 15; t++) for(int s = 0; s < 50; s++) for(int t = 1; t < 15; t++) for(int s = 1; s < 50; s++)
