Question

Alice is designing a book shelf. The segment LQ represents the base of the book shelf. Alice wants to construct a line to represent a rack passing through R and parallel to side LQ. She uses a straightedge and compass to complete some steps of the construction as shown

Which of these is likely to be her next step in constructing the rack parallel to LQ?

Place the compass at S and adjust its width to point P.

Without changing the width of the compass, fix the compass at P and draw an arc.

Without changing the width of the compass, place the compass at S or P and draw an arc similar to the one drawn.

Place the compass at N and adjust the width to a length that is greater than the length of segment NS.

I think its B can someone please help me???
