Answer:
The answer is b) increased production of heat-shock proteins
Step-by-step explanation:
High temperatures release a cascade of signals that drive the expression of some genes and the synthesis of so-called stress proteins, whose function is to stabilize the structure of proteins and enzymes and are involved in the protection of the photosynthetic system and stabilization of the membranes. Plants produce antioxidant and detoxifying enzymes to reduce the damage caused by reactive oxygen species, since the production of these substances is caused by heat stress.
