The effector in a negative feedback loop works to bring the variable back to its normal range by opposing the initial stimulus. Once the variable returns to its normal range, the effector shuts off. This is how homeostasis is restored in a negative feedback loop. Options A, B and D do not accurately describe the function of the effector in a negative feedback loop.
