How does the dimeric structure of motor proteins facilitate their function in cellular transport?

• A. The heads and tails both bind to microtubules, facilitating movement.
• B. The two heads bind to microtubules and hydrolyze ATP, while the tail binds to cargo.
• C. The two tails bind to microtubules and hydrolyze ATP, while the head binds to cargo.
• D. The dimeric structure allows for random movement along microtubules.
