Step-by-step explanation:
1. Technician A states that many automotive lightbulbs have more than one filament inside. While this statement is true for some automotive lightbulbs, it is not universally true for all automotive lightbulbs. Some lightbulbs do have multiple filaments, while others may only have one filament.
2. Technician B states that some lights use a filament made of quartz. This statement is also true. Quartz is a material that is commonly used for filaments in certain types of automotive lights. The use of quartz filaments can provide advantages such as increased durability and longer lifespan compared to traditional filaments.
Therefore, Technician B is correct in stating that some lights use a filament made of quartz.
