Select the most appropriate option to fill in blank no. 5.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. may.
Context: The sentence explains that if wrong or incomplete data is stored, it has the possibility of becoming a permanent source for use. The blank should express possibility, not certainty.
Meaning of the words:
• may – expresses possibility
• must – expresses compulsion or necessity
• have to – shows obligation
• should – expresses advice or recommendation
Correct word: may
Reason: Here the writer is warning that incorrect data may become a permanent source, meaning it is possible but not guaranteed. Words like must or have to would make the statement too forceful and incorrect in this context.
Final Sentence: Incorrect or incomplete data may be stored, and this may become a permanent source and used for any given purpose.
Hence, the chosen option is correct.
