D Correct answer
Explanation

Indian Railways uses fish plates (metal bars used to join rail ends) with a standard thickness of 20mm. This thickness provides adequate strength to maintain rail alignment under train loads while allowing for the necessary bolt connections. The other options (16mm, 10mm, 25mm) are not the standard specification used by Indian Railways.
