Explanation:

When working on electrical components like a starter motor, safety is key. Disconnecting the negative battery cable first is a standard safety practice. This helps prevent accidental short - circuits. The negative cable is often considered the "ground" reference. By disconnecting it, the electrical circuit is broken in a way that minimizes the risk of electrical shock or damage to components during the removal process.

Answer:

B. disconnect the negative battery cable.
