Best Answer Explained in Below-:

The sentence "Though it is raining ____" sets up a contrast between the situation (rain) and the action (going). The phrase "though it is raining" implies that the speaker acknowledges the unfavorable condition but intends to indicate that the action will still occur.

Option D, "he will go," directly follows this contrast without adding any unnecessary conjunctions or qualifiers. It effectively completes the thought by stating directly that despite the rain, the action of going will take place. It aligns perfectly with the structure of the sentence, maintaining the simplicity and clarity of the message.

In contrast, options A, B, and C introduce additional elements that may complicate the meaning. For example, option A ("yet he will go") implies a more formal and slightly more complex relationship between the rain and the action, which may diminish the directness intended in the original sentiment. Similarly, options B and C ("as he will go" and "still he will go") introduce additional nuances that are not necessary for the straightforward acknowledgment of the situation.

Thus, "he will go" is the most concise and effective completion of the sentence, making it the correct choice.
