A. Yes
B. No

Answer 1

Yes, "adder" is a valid identifier in a VHDL program because it complies with the rules for VHDL identifiers, which require starting with a letter and only including letters, numbers, and underscores.

Step-by-step explanation:

The question asks if "adder" is a valid identifier in a VHDL program. Yes, adder is a valid identifier in VHDL. VHDL stands for VHSIC (Very High Speed Integrated Circuit) Hardware Description Language. It is used in electronic design automation to describe the behavior and structure of electronic systems. In VHDL, identifiers are used to name various elements such as variables, constants, signals, and entities. A valid identifier must start with a letter and can only include letters, numbers, and underscores. Since "adder" satisfies these criteria, it is a valid identifier.
