When the letter A is represented as 41h, it is displayed in which of the following?

The letter A being represented as 41h indicates that it is in hexadecimal format. The notation "h" signifies that the number preceding it, 41, is in base-16, which is characteristic of hexadecimal representation. In the ASCII table, the letter A is indeed represented by the decimal value 65, which converts to 41 in hexadecimal.

This representation confirms that the character encoding corresponds to the hexadecimal system, making the association of A as 41h definitive in this context. The significance of hexadecimal is paramount in computing and digital electronics, where it is frequently used as a more human-friendly representation of binary-coded values.

The other representations, such as ASCII, Binary, and Decimal, relate to different systems of encoding and numerical representation, but the presence of the "h" indicator clearly identifies the hexadecimal format as the correct answer.
