Ravi at the end of the letter will attach a _________ for the reference.

Bio-data

The most suitable option to fill in the blanks is Bio-data.

The advertisement clearly states that the candidate must apply with their bio-data. A bio-data is a summary of a person's personal and professional qualifications. It typically includes the person's name, address, contact information, education, work experience, and skills.

The other options are not as suitable. An essay competition certificate is not a relevant document for the job application. A birth certificate is a document that proves a person's age and citizenship. An MBA group photo is not a professional document and should not be attached to a job application.
