B and C are correct. An ammeter is a low resistance device. A semiconductor material has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. As the temperature increases, their resistance decreases.
A and D are incorrect. A neutron is a sub-atomic particle that has no charge. One µA is equal to 10-6 A. An ampere is a bigger unit. Micro-ampere (µA) is a smaller unit.

The statement "A neutron has a positive charge of 1.6" is incorrect.

Neutrons are electrically neutral particles, meaning they do not have a positive or negative charge. They have a neutral charge, with no overall charge.
