Which of the following best describes binary addition?

Binary addition specifically refers to the process of adding sequences of bits, where each bit can only take on the value of 0 or 1. This method is foundational to digital electronics and computer systems, as it aligns with how computers operate using binary code. Each bit added will follow the rules of binary arithmetic, where 0 + 0 = 0, 1 + 0 = 1, 0 + 1 = 1, and 1 + 1 results in a carry to the next higher bit place, represented as 0 with a carry of 1.

While adding two decimal numbers and combining integer values can involve binary addition when those values are converted to binary, these activities are broader and not limited to the binary system itself. Thus, they do not define the primary operation of binary addition, which is strictly the manipulation of bits in a binary format. A. and C. encompass wider concepts that go beyond the specific operation of binary addition. Hence, focusing on the addition of sequences of bits provides the precise definition of binary addition.
