The word ‘assessment’ means –

The answer is C) Evaluation. Assessment means the act of judging the worth, quality or level of something, which is what evaluation means too. The question tests whether you know this close synonym.

• Enquiry is a systematic investigation to establish facts, such as a judicial or departmental enquiry. It asks what happened, not how good something is.
• Report is a written account of findings. It is the output of an assessment, not the act of assessing.
• Summary is a condensed version of a longer text. It reduces content and does not judge it.

Core concept: synonyms and precise word usage in English comprehension. On the Mains side, the idea runs through governance, from CAG performance audits to NITI Aayog's assessments of state performance, and in education through the continuous and comprehensive evaluation introduced under the RTE Act, 2009.

Trap: choosing Report because assessments are usually reported. Read the word as the act of judging, not the document that results from it.
