Answer: (E)

Verified step by step guidance

1. Identify the ligands attached to the metal cation in the complex. From the image, there are two chloride ligands (Cl\^-) and two ammonia ligands (NH\_3).
2. Determine the charge of each ligand: chloride (Cl\^-) has a charge of -1, and ammonia (NH\_3) is a neutral ligand with a charge of 0.
3. Calculate the total charge contributed by the ligands: 2 chloride ligands contribute 2 \(\times\) (-1) = -2, and 2 ammonia ligands contribute 2 \(\times\) 0 = 0, so the total ligand charge is -2.
4. Note the overall charge of the complex ion, which is given as 0 (neutral complex).
5. Set up the charge balance equation where the charge of the metal cation (x) plus the total ligand charge equals the overall charge: x + (-2) = 0. Solve for x to find the charge of the metal cation.
