Yes ,kinda I think an English word can have more than one prefix for example like:antidisestablishment,unpremeditated......
It's PQRS, the one in the middle
The answer is most likely C.
A clause has a subject and a verb, so
1) "parade" "began"
2) "she" "loves"
3) "she" "went"
4)
5) "today" "rained"
so by this logic 4 wouldn't be a clause because it has no identifiable subject or verb
