If deletion of a control element causes a decrease in gene expression, what must be the normal role of that control element?

a. To repress gene expression; the level of gene expression increases because repressors are not able to bind to the enhancer without the control element.

b. To activate gene expression; the level of gene expression increases because repressors are not able to bind to the enhancer without the control element.

c. To repress gene expression; the level of gene expression decreases because activators are not able to bind to the enhancer without the control element.

d. To activate gene expression; the level of gene expression decreases because activators are not able to bind to the control element.
