I feel like hydrogen cyanide has some unusual effects, but I can't recall the specifics. Maybe it's option D?

I remember practicing a question about toxicants, and I think it was classified under sensory irritants, but that doesn't feel right for cyanide.

I've got a good feeling about option B. Asphyxiants make the most sense for hydrogen cyanide based on what I know.

Okay, let's see. Hydrogen cyanide is a pretty nasty chemical, so it's probably in the "toxicants exhibiting other unusual effects" category.

Hydrogen cyanide is definitely an asphyxiant. It inhibits cellular respiration, causing suffocation. B is the correct answer.
