The answer is disinfectants. Milady's definition matches this question closely: "disinfectants are products that destroy most bacteria (not including spores), fungi, and viruses on surfaces." That "not including spores" qualifier is the deliberate distinction from sterilization (see the question above) — disinfectants are strong, but sterilization is the only category that also reliably kills spores.
Cleansers, sterilizers, and sanitizers — the other choices — describe related but distinct steps in the same process; disinfectants specifically are the surface-level chemical products this question is asking about, one step below full sterilization.
