The correct answer is rocks glass, which is specifically designed for serving whiskey on the rocks. A rocks glass, often referred to as an Old Fashioned glass or lowball glass, has a short and sturdy design perfect for holding a small amount of liquor with ice. This style allows for the drink to be sipped comfortably while also allowing the drinker to enjoy the aroma of the whiskey, enhancing the overall tasting experience.

When whiskey is served on the rocks, the ice helps to chill the drink without diluting it too quickly, as the rocks glass typically holds just the right volume for this purpose. The shape and size of the rocks glass also encourage the right amount of mixing when you gently stir in the ice, ensuring the whiskey maintains its character while being served at a suitable temperature.

The other glass types mentioned don't serve this purpose effectively. Collins glasses are taller and narrower, designed for mixed drinks with more volume; highball glasses are also taller but primarily used for long drinks with a greater liquid capacity; shot glasses are small vessels meant for quick shots of liquor. Each of these alternatives does not align with the traditional way whiskey on the rocks is enjoyed, making the rocks glass the ideal choice.
