Statement 2: Manganese has $5$ electrons in the $3d$ subshell.

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1.
• B. If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation o f the statement 1.
