A. She washed the shells and dried them in the sun.
<span> The sentence is “She washed the shells and dried them in the sun”. A compound predicate actually consists of two or more than two verbs having the same subject and joined by any conjunction like “or” or “and”. As far as the given sentence is concerned, we see that “She” is the subject and the subject is doing two different things. This is the reason behind taking this sentence as a compound predicate. </span>
"Who knows but this surrendered face were undefeated still." If something surrenders, it implies it has been defeated. "Heavenly hurt" does seem to be ironic too though. Hope this helped.

Explanation:
Series of items: When there are a series of items, the comma can be used to separate them e.g. I went to the market and bought rice, yam, beans and egg.
Introductory word or phrases: The comma can be out after an introductory word or phrase e.g. However, the dog bit the boy.
Interrupting phrases: The comma can be used for an interrupting phrase to give more information.
Compound sentences: Comma can be placed between compound sentences even though each sentence can stand on its own e.g. Tom doesn't like mangoes, so he threw them away.
