This sentence contains a noun clause

Explanation:

A noun clause is the dependent clause that acts a as a noun in the sentence. It usually begins with the words, how, whenever, whichever, when, where, who, whom, why, whether. They can either act as subject or object (direct or indirect) of the sentence. They may also act as objects of preposition.

Option D has the noun clause "Whenever we choose to leave for the game". It is acting as a subject of the sentence here. The 'verb' in the sentence is 'choose'.
