The answer is D. This is referred to as reflex reaction. Reflex is the instantaneous and involuntary reactions to a stimuli. Reflex arc does not pass through the brain so the reaction time is shorter than normal. This is a adaptation to increase survival.
Explanation:
E, will be lower- this denotes the activation energy
Activation energy is the specific amount of energy required for a chemical reaction to occur. Enzymes lower the activation energy, significantly speeding up the reaction rate.
Further Explanation:
Enzymes are proteins that catalyze reactions by working on substrates to promote reactions-including amylase breakdown of broad polysaccharides. Some enzymes like catalase, allow for the degradation of hydrogen peroxide into oxygen and hydrogen; the pH, temperature, and involvement of inhibitors influence their specificity.

Hope it helps! :)
3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.
