Which type of whisky is blended from one or more Single Malt and Single Grain Scotch Whiskies?

Blended Scotch Whisky is the correct answer because it is specifically defined as a type of whisky that combines one or more Single Malt Scotch Whiskies and one or more Single Grain Scotch Whiskies. This blending allows for the creation of a more complex flavor profile and consistency in taste, which can appeal to a wider audience.

Single Malt Scotch Whisky refers solely to whisky made from malted barley at a single distillery, without the inclusion of any grain whisky. Similarly, Single Grain Scotch Whisky is produced at a single distillery but can include grains other than barley. Blended Grain Scotch Whisky involves blending multiple grain whiskies, which does not encompass the single malt aspect. Therefore, only Blended Scotch Whisky encompasses both the single malt and single grain components required for its classification, making it the correct choice.
