Explanation:

• When forming the passive voice with modal verbs like can, may, should, would, must, the structure is:
  modal + be + past participle (V₃)

Examples:

• Active: I can do it. → Passive: It can be done by me.

• Active: They should complete the project. → Passive: The project should be completed by them.

• Active: He would sing good songs. → Passive: Good songs would be sung by him.

• Active: She may use the tubewell. → Passive: The tubewell may be used by her.

Why other options are wrong:

• খ) The project should completed by them.  be is missing; correct form is should be completed

• গ) Should the project be completed by them.  This is a question form, not a statement

• ঘ) The project completed should by them.  Word order is incorrect; passive rules not followed
