Answer 1

Here must indicates an obligation.

• In the English language, we use the word 'obligation' when a thing has to be done certainly.
• Must refers to when we are obliged to something or when something is necessary.
• For example, you must write the letter. You must go to the market. You must work hard to achieve success. In all these statements, the word 'must' makes it obligatory to do the tasks.
