Why is specificity in vesicular transport crucial, and how do SNARE proteins ensure this specificity?

• A. Specificity prevents vesicles from fusing with incorrect membranes, and SNARE proteins ensure this by matching v-SNAREs with the correct t-SNAREs.
• B. Specificity is achieved through the hydrolysis of ATP by SNARE proteins, which guides vesicles to their target.
• C. Specificity is not crucial as vesicles can fuse with any membrane, and SNARE proteins are not involved in this process.
• D. Specificity is ensured by the random interaction of vesicles with membranes, and SNARE proteins only provide structural support.
