Correct Option: গ) enough

Full Sentence: He is smart enough to move from the place.

English Meaning: He has sufficient intelligence or cleverness to move from the place.

Bangla Meaning: সে জায়গা ছেড়ে যাওয়ার মতো যথেষ্ট বুদ্ধিমান।

Grammar Note: এখানে structure হলো “adjective + enough + to-infinitive”। এটি কোনো ব্যক্তির কোনো কিছু করার যোগ্যতা বা সক্ষমতা প্রকাশ করে।

• এখানে “smart” হলো adjective

• আর “enough” বোঝাচ্ছে তার বুদ্ধিমত্তা যথেষ্ট, যাতে সে সেই কাজটি করতে পারে।

Other Options:

ক) about

• Meaning: concerning or relating to (সম্পর্কে)

• এই প্রেক্ষাপটে grammatically fit করে না।

• Example: He is worried about his exams.

খ) too

• Meaning: more than necessary or acceptable (অত্যধিক)

• “Too” সাধারণত "to + verb" এর আগে আসে কিন্তু এর মানে negative হয়।

• Example: He is too smart to be fooled.

• এখানে positive অর্থ দরকার, তাই enough সঠিক।

ঘ) so that

• Meaning: in order to (যাতে)

• এটি সবসময় subject + verb clause চায়, infinitive না।

• Example: He is smart so that he can solve any problem.

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
