The correct answer relates to the safety and reliability of electrical connections in a lighting fixture. Unnecessary splices or taps within or on a lighting fixture can create points of failure, increase fire risks, and complicate future maintenance.

Lighting fixtures are designed to be both functional and safe, and unnecessary splices can lead to issues such as overheating or arcing, potentially compromising the electrical integrity of the entire fixture. For reasons of safety and to maintain optimal electrical performance, it is crucial that any splices or taps made in a lighting fixture are necessary for its proper operation.

In contrast, the other options represent conditions that could be acceptable under certain circumstances but do not encapsulate the broader implication of safety and functionality associated with "unnecessary" splices. Permanent connections, if done correctly, are critical for ensuring reliability, while temporary connections might sometimes be used for testing or maintenance purposes. Loose connections may be problematic, but that isn’t inherently prohibited under the same reasoning as unnecessary splices being avoided altogether in lighting fixtures.
