Statement 2: ${\left[Cr{\left(N{H}_3\right)}_6\right]}^{3+}$ shows $d^{2}s{p}^3$ hybridisation.

• A. Statement 1 is True, Statement 2 is True; Statement 2 is correct explanation for Statement 1
• B. Statement 1 is True, Statement 2 is True; Statement 2 is not correct explanation for Statement 1
• C. Statement 1 is True, Statement 2 is False
• D. Statement 1 is False, Statement 2 is True
