Answer:
Incomplete.
Explanation:
As per the question, the given sentence would be characterized as an 'incomplete' sentence as it is syntactically and semantically fragmented. It comprises of two subordinate clauses which fail to convey a coherent thought. Grammatically, a subordinate clause is accompanied by an independent clause to accomplish its meaning but here the sentence involves two subordinate clauses back to back which leaves the meaning unaccomplished.
In order to rectify the error, the second subordinate conjunction(i.e. 'before') could be removed to make the latter clause of the sentence independent and add a comma(,) after the subordinate clause so that they together(subordinate clause followed by the principal clause) convey a coherent thought(syntactically and semantically appropriate). It read as:
'After copying the information, you begin the following steps.'
The dance squad had eight members when it won the competition.
A relative clause can be used as an adjective or an adverb. Relative clauses must contain both a subject and a verb. They also begin with a relative pronoun (question words and that). The relative clause in the last option is "when it won the competition". It starts with "when" which is a relative pronoun. It describes when the action takes place which makes the entire clause an adverb. It has a subject "it" and a verb "won". Options B and C should be immediately thrown out because they do not have a relative pronoun. Option A does not work because there is no subject after "that".
A. Because you can picture it while the others are harder to picture.
