What is the product of inner deiodination of T4?

Explanation:
Inner deiodination of T4 removes the iodine from the inner ring, producing reverse T3, an inactive metabolite. Outer ring deiodination, in contrast, removes the outer-ring iodine to make T3, the active hormone. So the product of inner deiodination is reverse T3. The other options aren’t products of this pathway: TSH is a pituitary hormone, T4 is the substrate, and T3 is produced by outer ring deiodination.
