Question

Explanation:

After a solder repair, heat - shrink tubing with sealant is a common way to protect the repair. It provides both mechanical protection and electrical insulation. Dielectric grease and RTV sealant are not the best for this purpose alone. Duct tape is not suitable for long - term electrical protection. And leaving it unprotected is not advisable.

Answer:

C. Heat shrink tubing with sealant
