pH below its optimal range

Increase in substrate concentration
Increase in substrate concentration

Presence of an inhibitor
Presence of an inhibitor

Slight temperature increase

Answer 1

pH below its optimal range
Presence of an inhibitor

(An increase in substrate concentration usually increases activity (until saturation), and a slight temperature increase generally increases activity unless it causes denaturation at high temperatures.)
