Final answer:

B) Carnitine Palmitoyltransferase I

The rate-limiting step of beta-oxidation is Carnitine Palmitoyltransferase I (CPT I), which is essential for the transport of activated fatty acids into mitochondria.

Step-by-step explanation:

The rate-limiting step of beta-oxidation is Carnitine Palmitoyltransferase I (CPT I). Beta-oxidation is a metabolic process involving the oxidation of fatty acids to produce energy.

The steps in beta-oxidation include the activation of the fatty acid by Acyl-CoA Synthetase, the transport of the activated fatty acid into mitochondria facilitated by CPT I, the successive removal of two-carbon units by enzymes including Acyl-CoA Dehydrogenase and ß-Hydroxy Acyl-CoA Dehydrogenase, and the final release of acetyl-CoA.
