Which among the following methods can be used to separate heterogeneous mixtures into their respective constituents?

The correct options are
A Handpicking
B Filtration
C Sieving
A heterogenous mixture contains physically distinct parts and have non-uniform composition.

• Sieving is typically used for separating particles by size through a mesh as we notice near construction sites.
• Filtration is a method used for separating an insoluble solid from liquid using a filter paper.
• Handpicking is a method used to separate a mixture using hands.
• Distillation is a process used to separate components of a homogenous mixture. It involves heat and a sophisticated apparatus and does not come under 'simple physical methods.'

So, sieving, handpicking and filtration are simple physical methods used to separate a heterogeneous mixture.
