We know that the profit is equal to the revenue minus the cost. The revenue earned from selling $G$ glasses of lemonade at $1.75 per glass is $1.75$G$. The cost includes the cost of sugar and lemons used, which is $1.62 per pound of sugar and $0.64 per lemon, respectively. So, the cost is $1.62$S$ + $0.64$L$. Therefore, the profit can be expressed as:

$$P = 1.75G - 1.62S - 0.64L$$

This is the formula given in choice (A), which makes it the correct answer.
