Final Answer:
Queries may be scheduled to run at a specific date and time, and the scheduling options provided are: a) Only on weekdays.
Step-by-step explanation:
The question addresses the scheduling of queries at a specific date and time. Among the given options, "Only on weekdays" implies that the queries can be scheduled exclusively from Monday to Friday. This scheduling restriction ensures that the queries are executed during the standard workweek, excluding weekends. The other options, such as "Anytime during the week," "Only on weekends," and "Only during office hours," do not precisely match the specified condition of running queries on weekdays. Therefore, the correct choice is option a) "Only on weekdays."
Option A is the answer.
