Step 1: Analyze the Hindi sentence. "अध्ययन करो" (adhyayan karo) is an imperative verb, meaning it is a command or piece of advice: "Study!".
Step 2: Translate the adverb. "नियमित रूप से" (niyamit roop se) is an adverb meaning "regularly".
Step 3: Combine the parts correctly. In English, an adverb modifies a verb. The adverb 'regularly' should modify the verb 'study'.
Step 4: Form the correct command. The correct English imperative is "Study regularly." Option (B) is incorrect because 'regular' is an adjective, not an adverb.
