The symbol for a logical "AND" operation is typically represented by a standard AND gate in digital logic. The options you've provided suggest that you're possibly looking for which logic gate corresponds to the symbol you referred to as "a(n)."
If "a(n)" refers to logical AND and you're asking for its gate symbol, then the answer would be:
AND gate
However, if "a(n)" corresponds to a different logical operation, you may need to specify that for a more accurate answer. Please let me know if you have any additional context or details!
