Arrange the following steps in the correct sequence to charge a single metal sphere positively by electrostatic induction using a negatively charged plastic rod: 1. Bring the negatively charged rod close to the uncharged metal sphere without touching it. 2. Disconnect the ground connection while keeping the charged rod in place. 3. Connect the metal sphere to the ground (earthing) while the rod is held near. 4. Remove the negatively charged rod, allowing the positive charge to distribute uniformly over the sphere. Select the correct sequence from the options given below:

Options:

• A: 1 -> 2 -> 3 -> 4
• B: 1 -> 3 -> 2 -> 4
• C: 3 -> 1 -> 2 -> 4
• D: 1 -> 3 -> 4 -> 2
