Which sentence uses a form of bet, put or hurt correctly?

Explicación

Bet does not change its spelling for the past, so "I bet twenty pounds on that match last night" leaves the base untouched exactly as this group requires. The other two sentences bolt the regular -ed ending onto verbs that refuse it: put and hurt are invariant as well, so hurted is not an English form at all, and putted belongs only to the separate golf verb putt, never to put in the sense of placing something.
