The correct answer is (c) broth.
Proverb: "Too many cooks spoil the broth."
Meaning: When too many people are involved in managing something, the result is often worse than if fewer people had been involved.
Bangla meaning: বেশি লোক কোনো কাজে হস্তক্ষেপ করলে সেই কাজ নষ্ট হয়। অনেক মাথায় কাজ হয় না।
Note: The standard proverb uses "Too many cooks" (not "Too much cooks" — the question contains a deliberate grammatical error to test the idiomatic knowledge of the missing word).
Broth (ব্রথ) = একটি পাতলা মাংসের ঝোল, soup; ঐতিহ্যবাহী রান্নার উপাদান।
