Answer:
Option B is spelled incorrectly
The kind of verbs in this statement are "states of being" verbs or linking verbs since they describe conditions that exist and are also inactive since no action is performed. The sentence uses present tense, but as stated before they do not perform any action. Since the verbs they are using them most are: is, have, feel and do.
