The correct answer is D. No improvement.
The sentence “He enjoys nothing more than drawing swords with others” is grammatically correct and conveys the intended meaning clearly. The word “drawing” is used in the sense of “to take out (a sword) from its sheath.” The word “swords” is plural, which indicates that the speaker is referring to more than one sword. The word “with” indicates that the speaker is referring to two or more people who are drawing swords together. The word “others” is a pronoun that refers to the people who are drawing swords with the speaker.
The other options are not as effective in conveying the intended meaning. The word “crossing” could be interpreted to mean “to meet or intersect.” The word “playing” could be interpreted to mean “to engage in a game or sport.” The word “clashing” could be interpreted to mean “to come into violent contact.”
Therefore, the correct answer is D. No improvement.
