fill in the blank.\nthe rider tugged on the ______ of her horse to make him slow down.\n reins\n ranes\n…

Brief Explanations:

To solve this, we analyze the context: a rider slowing a horse involves using "reins" (straps to control the horse). "Ranes" is not a valid term, "rants" means angry outbursts, and "reigns" refers to ruling (e.g., a monarch's reign), so none fit except "reins".

Answer:

A. reins
