Choose the correct answer from the options given below:

(D) Only

The correct answer is Option (1) - (D) Only

• The common expression is "kind to someone." In this context, the sentence "He is very kind to us" uses the preposition "to" to indicate the direction of kindness.
• The other options do not fit naturally with the adjective "kind" in this sentence.

Thus, the correct completion is: He is very kind to us.
