A mixture M is made up of two components, P and Q. P is visibly larger and of a different colour than Q. Which of the following processes can be used to separate P and Q?

The correct option is C Handpicking
Handpicking is used for separation when the differences between the components are clearly visible. These differences can be in terms of colour, size and shape. Also, the particle size should be large enough to be handpicked. Since P and Q are visibly different and particles of P are large in size, they can be easily separated by handpicking.
