Neha and Imran were given an assignment on the coordination complex $[\text{Co}(\text{NH}_3)_6]\text{Cl}_3$. They had to find the hybridisation involved and the magnetic behaviour of the complex compound. Neha found that the complex compound was of $\text{sp}^3\text{d}^2$ hybridisation and paramagnetic in behaviour whereas, Imran found that the complex compound was of $\text{d}^2\text{sp}^3$ hybridisation and diamagnetic in behaviour. Evaluate the responses of Neha and Imran.
