White crystalline solid (A) reacts with ...

White crystalline solid (A) reacts with `H_2` to form a highly associated liquid (B) and a monoatomic , colourless gas (C ). The liquid (B) is used for etching glass. Compound (A) undergoes hydrolysis slowly to form (C ), (B) and a diatomic gas (D ) whose IE is almost similar to that of (C ). (B) forms an addition compound with KF to form (E) which is electrolysed in the molten state to form a most reactive gas (F) which combines with (C ) in 2:1 ratio of produce (A).
According to Molecular Orbital Theory, which of the following is correct about the molecule (D) ?

A

Its bond order is 2

B

It has two unpaired electrons in `sigma` molecular orbital

C

It is diamagnetic

D

It has only unpaired electron in `pi` molecular orbital.
