Writing for business - wreckless or reckless

Which is correct?

The bank’s ________ lending practices are at least partly to blame for its current financial woes.
a. reckless
b. wreckless

Answer: a

Explanation: Wreckless is an incorrect spelling for the word reckless.

The word reckless means “without caution” or “without thinking about the consequences.”  The word wreck means “ruin.” It’s true that performing actions without thinking of the consequences may ruin something, but there’s no such word as wreckless.
