Answer:
Most women will experience postpartum depression after giving birth to a child.
Explanation:
Option C contains a run-on sentence (I would call it a comma splice).
A better way to phrase the sentence could be:
1. A giant clam grows huge; it can weigh hundreds of pounds.
2. A giant clam grows huge. It can weigh hundreds of pounds.
When we say participles, these are words which taken the verb forms both in the -ing form (present) and the -ed or -en form (past), but these function as adjectives only. So based on the given statement above, I can say that it is TRUE since participles can be used in order to shorten the subordinate clause. Hope this helps.
