Answer

  1. Both assertion and reason are true but reason is not the correct explanation of assertion.

Solution:

At first several principles are present which makes whisky harsh and unpalatable. It must be aged to allow these principles to disappear. The whiskies are aged in charred oak containers. At first the whisky is colourless, the colour develops during the aging process. The vodka is not aged and bottled immediately after distillation and therefore it remains colourless.
