The d - orbitals involved in `sp^(3)d^(2)` hybridisation are ……………..and …………….

Explanation

To determine the d-orbitals involved in sp³d² hybridization, we can follow these steps:

### Step 1: Understand Hybridization
Hybridization is the concept of mixing atomic orbitals to form new hybrid orbitals that can accommodate the bonding electrons in a molecule. In sp³d² hybridization, we are dealing with a combination of s, p, and d orbitals.

### Step 2: Identify the Hybridization Type
The notation sp³d² indicates that we are combining:
- 1 s orbital
