Poor wiring practices can significantly compromise electrical safety and performance. The correct response highlights that such practices may create excessive heat or arcing, which are critical risks. When wiring is not properly installed, it can lead to increased resistance in the electrical circuit. This resistance generates heat, which can cause insulation to break down and potentially lead to short circuits or fires.

Arcing occurs when electrical current jumps between conductive materials, which can happen due to loose connections or damaged wires. This can further exacerbate heating issues and pose a dangerous risk of igniting surrounding materials. Overall, the potential consequences of poor wiring practices underscore the importance of adherence to safety standards and proper installation techniques to mitigate these hazards.

The other choices fail to capture the severity of the risks involved; voltage fluctuations may occur but do not inherently imply the same level of danger as excessive heat or arcing does. Labeling poor wiring as "generally safe" is misleading and ignores the serious implications. Additionally, stating that poor practices improve electrical flow is inaccurate, as improper wiring tends to hinder performance rather than enhance it.
