Answer 1

C. "At one time there were a large number of Tasmanian wolves, predominantly found in Australia, but people hunted them down because they at times killed chickens and sheep."

Explanation: "predominantly found in Australia" is a nonrestrictive appositive and should be set off with commas; a comma is also needed before "but" joining two independent clauses.
