The correct answer is B. Decided
Explanation:
In grammar, verbs can be classified as action verbs or as linking verbs. In the case of action verbs these are verbs that directly express an action performed by a subject, this action can be mental or physical, but always imply something an object, animal or person does examples of this verb include help, play, run, ask, etc. This differs from linking verbs, because in linking verbs such as be, feel, seem do not express an action but connect the subject with other words to describe a condition or state of the subject. Considering this, in the case of the sentence "I decided that even a hot day in New Mexico feels comfortable because of the dry air" the action verb is "decided" because this is the verb that expresses a direct action the subject "I" performs.
