Step 1: The adjective "easy" is being compared between two things, so the comparative form "easier" is needed.
Step 2: The other options are grammatically incorrect or not suitable for comparison. "More easy" is redundant, "much easy" is incorrect, and "easiest" is a superlative, which is used for comparing three or more things.
Step 3: Thus, the correct answer is (D) easier.
Final Answer: (D) easier
