He was in high spirits when I met him in the restaurant. A. He was in a drunken state B. He was very cheerful C. He talked incoherently D. He was deeply engrossed in thoughts

The correct answer is: B. He was very cheerful.

The phrase “in high spirits” means to be in a happy and excited mood. This is consistent with the description of the man in the restaurant, who was talking and laughing with his friends.

Option A is incorrect because it suggests that the man was drunk. There is no evidence to support this claim, and in fact, the man’s behavior suggests that he was sober.

Option C is incorrect because it suggests that the man was talking incoherently. There is no evidence to support this claim, and in fact, the man’s behavior suggests that he was speaking clearly and coherently.

Option D is incorrect because it suggests that the man was deeply engrossed in thoughts. There is no evidence to support this claim, and in fact, the man’s behavior suggests that he was engaged in conversation with his friends.
