Consider the following statements for superconductivity: 1. Superconducting magnets capable of generating high fields with low power consumption are currently being employed in scientific test and research equipment. 2. One of the potential applications of superconducting materials is electrical power transmission through superconducting materials- power losses would be extremely low, and the equipment would operate at low voltage levels. 3. Type II superconductors are preferred over type I for most practical applications by virtue of their higher critical temperatures and critical magnetic fields. Which of the above statements is/are correct?

Answer: Option D
