How is food transported to food vacuole of paramecium?

The correct option is A

By movement of cilia

Paramecium uses cilia to sweep food particles along with some water into an oral groove (a groove present on the surface of paramecium). At the end of the oral groove, a food vacuole gets created. This food vacuole further travels throughout the cytoplasm and during this journey, the food inside the vacuole gets digested and absorbed.
