Answer 1

Correct choice is (d) rails

Easiest explanation: Horizontal boards at the top, bottom, and optionally in the middle of a door that join the two stiles and split the door into two or more rows of panels. The “top rail” and “bottom rail” are named for their positions. The bottom rail is also known as “kick rail”. A middle rail at the height of the bolt is known as the “lock rail”, other middle rails are commonly known as “cross rails”.
