Explanation: A) Software reuse has three basic steps: abstraction, storage, and recontextualization. Abstraction involves the design of a reusable piece of software, starting from existing software assets or from scratch. Storage involves making software assets available for others to use. Once an asset has been found, recontextualization–or making the reusable asset understandable to developers who want to use it in their systems–becomes important.
