Since Felicia missed four classes in a row, she is wholly unprepared for today's exam, which covers all the bones in the human body. a) fused sentence
b) comma splice

b). Comma splice

Explanation:

'Comma splice' is defined as the grammatical error in which the two self-sufficient sentences are inappropriately linked by using a comma. The given sentence contains this error of comma splice when it unnecessarily involves comma(,) before the relative pronoun in order to set out the essential information that it is being added to the sentence. Thus, option b is the correct answer.
