Question

the roadway marking to which the arrow is pointing means
a stop here for stop sign.
b one-way, do not enter.
c pedestrian crosswalk.
d no turns at this intersection.

Explanation:

The roadway marking with the arrow (and a stop sign nearby) is a stop line, which means drivers should stop here when approaching the stop sign. Option A describes stopping here for the stop sign. Option B is for a "do not enter" (usually a red circle with a line or a one - way wrong - way) marking, option C is for crosswalk lines (usually parallel lines for pedestrians), option D is for turn - prohibition markings (not related to this stop - related line).

Answer:

A. stop here for STOP sign.
