Final answer:
The correct ingredients for the Pluckers Lemonade are lemon juice, sugar, water, ice, and a lemon wedge, making option a) correct. This is a traditional lemonade recipe.
Step-by-step explanation:
The five ingredients in the Pluckers Lemonade, including the garnish, are lemon juice, sugar, water, ice, and a lemon wedge. This makes option a) the correct answer. This beverage is a simple and classic lemonade recipe, where the freshness of the lemon juice is complemented by the sweetness of sugar, the chill of ice, and the decorative and slightly flavorful addition of a lemon wedge as garnish. Unlike the other choices, which include ingredients for other specific drinks (e.g. cocktails like a Cosmopolitan in option d), this option reflects a traditional lemonade recipe.
