b. a mutagen
c. pyrophoric
d. a lachrymator

Answer 1

A dangerous chemical that causes an allergic reaction in some people, leading to potentially lethal anaphylaxis, would be described on the MSDS (Material Safety Data Sheet) as a sensitizer.

Step-by-step explanation:

A dangerous chemical that causes an allergic reaction in some people, leading to potentially lethal anaphylaxis, would be described on the MSDS (Material Safety Data Sheet) as a sensitizer. Sensitizers are substances that can cause an allergic reaction when exposed to the immune system, even at low doses. In this case, the chemical is known to cause severe allergic reactions in certain individuals that can be life-threatening.
