সঠিক উত্তর হচ্ছে: highest
ব্যাখ্যা: The correct choice is the word "highest." We know that this is the correct choice because there the word "the" precedes the blank, so we know that we are talking about a superlative, and the superlative form is "highest." It is not higher or high because they are not the superlative forms of the word. While "most" is also a superlative, it is not the best choice since we are talking about performance in sales, and performing the highest makes more sense than performing the most.
