Let's analyze each pair:
(A) The 38th Parallel Line separates North Korea and South Korea. Correctly matched.
(B) The McMahon Line indeed separates India and China, but the spelling error in “Indin” makes this pair wrongly matched grammatically.
(C) The Radcliffe Line demarcates the boundary between India and Pakistan. Correctly matched.
(D) The Maginot Line was a line of fortification built by France along its border with Germany. It has no connection to England, but the line itself was not meant between “Germany and England.” Hence this may also appear incorrect contextually, but based on standard MCQ formatting, the spelling error in (B) is usually considered first.
