The correct option is D blame the coach for not providing necessary training.
The passage is about the situation during the beginning of a game season, where a reporter questions a coach of a team about his players. The question is to pick out the direct consequence of the line "If a favourite team loses the game, its fans...". Option D is the correct consequence, as mentioned in the line from the passage, "if the team loses, he will be criticized for not making the most of his material", where "criticized" means to blame, and "not making the most of his material" is replaced by "not providing necessary training". Option A is incorrect because it's not mentioned anywhere that the fans would want to get the coach fired, but only blame him. Option B is incorrect as it's not mentioned anywhere that the team would be accused for their lack of commitment, only the effect on the coach is mentioned. Option C is incorrect because the passage does not state the effect on the fans, that they would be let down.
