The correct option is C lead to problems for him in case the team fails to win.
The given passage is about a situation during the beginning of the game season where a coach is to talk about his new team members. The question asks for the correct option which resonates in meaning to the passage. If the coach's team is elevated as his favourite, then it would "lead to problems for him in case the team fails to win", as suggested by the line "because if the team loses, he will be criticized for not making the most of his material". Option C means the same as the line just mentioned, hence C is correct. Option A is incorrect because it's not mentioned in any way in the passage that favouring his team would bring enthusiastic fans in the field. Option B is incorrect because it's not mentioned how the coach's praising would affect the players, the passage is written from the point of view of the coach. Option D is incorrect because the coach's praising his team players would not result in intimidating its rivals, but the coach would face problems if they did not live up to the praises he made.
