stupid

The correct answer is D. inadvisable.

The word “stupid” means “lacking intelligence or common sense.” It would not be accurate to say that it is stupid to go beyond a barricade, as there may be good reasons to do so, such as if there is an emergency.

The word “adventurous” means “willing to take risks.” It is possible that going beyond a barricade could be considered adventurous, but it is also possible that it could be considered dangerous.

The word “hazardous” means “full of or involving risk.” Going beyond a barricade could be considered hazardous, as there may be obstacles or dangers that are not visible.

The word “inadvisable” means “not recommended.” It is generally advisable to stay behind a barricade, as there may be risks involved in going beyond it.
