The task is to determine the major product formed when (R)-3-methylpent-1-ene reacts with Grubbs catalyst. The focus is on understanding how the reaction leads to the formation of a cyclic compound and the stereochemistry of the product. The correct answer is (R)-3-methylcyclopentene, which reflects the stereochemical outcome of the reaction."}
