Hyporeactivity is

Explanation:
Hyporeactivity means the response to a stimulus or drug is weaker than normal. So, the same dose produces a smaller effect, i.e., decreased intensity. This can happen when receptors become desensitized or downregulated, or when the intracellular signaling isn’t as effective. The other options don’t fit: increased intensity would be hyperreactivity, no effect would be zero response, and an irreversible effect implies lasting change beyond simply a reduced response.
