Correct option is C
The correct option to fill in the blank is (c) text message.
The context of the sentence discusses the improper use of customer-provided phone numbers, specifically referring to texting them without permission. The term "text message" is appropriate because it aligns with the concept of unauthorized communication via mobile devices, which has been a common cause of lawsuits.
Grammatical Rule Used:
- The noun chosen must precisely match the context of the sentence. "Text message" is relevant because it is a direct form of communication often associated with privacy concerns and legal restrictions.
Example:
There have been numerous complaints against companies for sending unsolicited text messages.
Meanings of the other options:
- Email (ईमेल): Refers to electronic mail, but the sentence clearly pertains to mobile communication, not emails.
- Memo (स्मरण पत्र): Refers to a written message in a workplace context, irrelevant to the given scenario.
- Letter (पत्र): Refers to a physical, written form of communication, which is not common in modern advertising disputes.
