Correct option is C
The correct answer is (c).
The primary function of the SNARE protein complex in vesicular transport is to facilitate the fusion of vesicles with their target membranes. SNARE proteins mediate the final steps of vesicle docking and fusion by forming a stable complex that brings the vesicle membrane and the target membrane into close proximity, allowing the exchange of contents between them. This process is essential for intracellular trafficking and communication between different compartments in the cell, such as the transport from the endoplasmic reticulum (ER) to the Golgi apparatus or vesicle release at the synapse.
Incorrect options-
Option (a) is incorrect because hydrolysis of GTP to GDP is mainly performed by GTPases involved in vesicle budding or motor protein activity, not SNAREs.
Option (b) is incorrect as structural support to microtubules is provided by proteins like MAPs (Microtubule Associated Proteins), not SNAREs.
Option (d) is incorrect because cargo transport along actin filaments is mediated by motor proteins such as myosins, not by the SNARE complex.
