The purified liquid collected after condensation of vapor
B
The heating source used to vaporize the liquid

Verified step by step guidance1
Understand the distillation process: it involves heating a liquid mixture to create vapor and then cooling that vapor to collect a purified liquid.
Identify the components in the setup: the mixture in the distillation flask, the heating source, the vapor formed, the condenser, and the collected liquid after condensation.
Recognize that the 'distillate' is the liquid that has been vaporized and then condensed back into liquid form, which is collected separately from the original mixture.
Distinguish the distillate from other parts: it is not the heating source, not the original mixture, and not the residue left behind after vaporization.
Conclude that the distillate refers specifically to the purified liquid collected after condensation of the vapor during distillation.
