B.Kids, wanting to follow in the footsteps of the clowning icon, approach him for guidance.
The subject of the sentence is "kids". The adjectival clause "wanting to follow in the footsteps of the clowning icon" should be completely ignored. For this question, I would completely cross it out. Approaches is the verb for the sentence. Approaches agrees with a singular third-person subject (He approaches, She approaches, It approaches). The plural form of approach needs to be utilized in this sentence, so approaches needs to change to approach (Kids approach).
