In Oracle SQL, adding hours to a date can be done using the INTERVAL keyword with appropriate clauses:
Option C: INTERVAL '12' HOUR
Adds exactly 12 hours to a date.
Option D: INTERVAL '720' MINUTE
Since 720 minutes equal 12 hours, this correctly adds 12 hours to a date.
Option F: INTERVAL '11:60' HOUR TO MINUTE
This interval represents 11 hours and 60 minutes, which effectively adds up to 12 hours.
Options A, B, and E contain incorrect syntax or do not match the required addition of 22 hours as specified in the question.
