Consider the following statements regarding transformers:\n\n1. In a step-up transformer, the primary coil has fewer turns than the secondary coil, which increases the voltage and decreases the current.\n2. Eddy current losses in the transformer core are minimized by laminating the core.\n3. A transformer can step up or step down both alternating current (AC) and direct current (DC) voltages.\n\nWhich of the statements given above are correct?

Options:

• A: 1 and 2 only
• B: 2 and 3 only
• C: 1 and 3 only
• D: 1, 2 and 3
