The Correct Option is A

Solution and Explanation

Tetrahedral complexes show $sp^3$ hybridisation, so low spin (pairing of electrons in the d-orbitals) is false for tetrahedral complexes.
Tetrahedral compIexes show $d-d$ transition due to high spin of $d$-orbitals.
Tetrahedral complexes are coloured due to the absence of symmetry and presence of unpaired electron in $d$-orbitals.

Concepts Used:

Coordination Compounds

A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.

Coordination entity:

A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.

Ligands:

A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
