The question asks: What character is used on both sides of a date to tell Access that it is a date and not division?

First, I note that the provided data for answer options is missing, so there are no alternatives listed to evaluate individually. Nevertheless, I can explain the concept and why the given correct symbol is used in Access.

In Microsoft Access (and in Jet/ACE SQL syntax used by Access), a literal date or time value must be enclosed in hash symbols (#) to be recognized as a date/time value rather than treated as a numeric or arithmetic expression. For example, the date January 15, 2025 would be written as #1/15/2025# in many regional settings, or #2025-01-15# in ISO-like formats, depending on locale. The two hash characters clearly delimit the date literal from surrounding code or operators, ensuring Access parses it as a date instead of performing a division operation (which would be indicated by a slash /).

Why other symbols would be incorrect: If you used slashes, dashes, or other non-delimiter characters without the surrounding hash symbols, Access would not be able to distinguish a literal date from a mathematical expression or a string. For example, 12/31/2024 might be interpreted differently depending on regional settings, and without hashes, Access could misinterpret the input. The slash symbol by itself is typically used as a date separator in display formats, not as a delimiter that signals a date literal to the engine. Hashes are the explicit quoting mechanism that tells Access, “treat this as a date value.”

In summary, the key concept is that dates in Access SQL or expressions are enclosed by # characters to designate them as date literals, preventing misinterpretation as arithmetic or other types of data.
