Question

this road sign means image of railroad crossing sign stop if traffic is approaching; three - way intersection; crossroad; railroad crossing

Explanation:

The road sign shows "RAILROAD CROSSING" (the text on the sign is "RAIL", "CROSSING", "ROAD" forming "RAILROAD CROSSING"). The option "railroad crossing" matches the meaning of this sign. The other options: "stop if traffic is approaching" is for stop signs in some contexts, "three - way intersection" is for a different intersection sign, and "crossroad" is a general intersection, not specific to railroad.

Answer:

D. railroad crossing (assuming the last option is D; if options are labeled differently, adjust the identifier. Here, the last option text is "railroad crossing", so the answer is the option with text "railroad crossing".)
