The most appropriate preposition to complete the sentence "The authorities are going to enquire _________ the standards of hygiene in the south district" is: into

Here's why:

• About: This preposition is too general and doesn't convey the sense of a thorough investigation.
• For: This implies searching for something specific, while the authorities are likely concerned with the overall level of hygiene.
• On: This preposition is not typically used in this context to inquire about standards.

Into suggests a deeper examination and exploration of the existing hygiene standards within the south district. It implies delving into details, procedures, and potential issues to gain a comprehensive understanding.
