Answer:
the option D is the right answer.
Explanation:
Option D shows a pathway where activation of the receptor would lead to an increase in gene expression. This is because in this option we can see that the transcription regulator is decreasing gene expression, but there is a receptor that is activated and that has the ability to inhibit the pathway, allowing the selected gene to be expressed efficiently. This is because the pathway shows two inhibitory steps, when this happens an activation is performed.
