Solution
The correct option is D Hydrogen
Hydrogen is a non-metal placed above group 1 as it has 1 electron in its valence shell. It resembles both alkali metals and halogens and, so it is difficult to decide its position. But all the other elements in the periodic table have fixed positions and, so option A is the correct answer.
