The cell mechanism of "active transport" involves the transport of insoluble chemicals across the membrane with protein acting as the carrier.

The above statement is FALSE.

Facilitated diffusion happens when large, insoluble membrane compounds are diffused for easy transportation. However, this transport does not require energy, therefore, it is a passive transport.

Active transport requires energy when moving molecules against a concentration agent. It requires for specific membrane transport proteins. Only a certain type of protein can move a certain type of substance.

The three main types of Active Transport are:
1) Sodium-Potassium Pump
2) Endocytosis
3) Exocytosis  

That statement is true.

Ithink that b is correct but just in case wait to see if someone else answers
