"You put too much salt in this soup! It tastes like the ocean! Furthermore, there are too many potatoes in here. It's a soup, not a mountain! Next time, just add a lot of love and follow the recipe!"

much: "Salt" is an uncountable noun. When complaining about an excessive amount, we use "too much."

many: "Potatoes" is a plural countable noun. To show an excessive amount, we use "too many."

a lot of: "Love" is an uncountable noun here. In a positive sentence, "a lot of" is the most natural choice. (The option "a lot" is incorrect because it is missing the preposition "of" before the noun).
