Answer 1

The most relevant option that is typically part of the knowledge base of research and development scientists working on heating devices is:

**substances and their properties**

Additionally, **engineering rules and principles** may also be part of their knowledge base, as these scientists often apply scientific and engineering principles in the design and development of new heating technologies. Marketing strategies and sales projections are typically more relevant to business and marketing roles rather than to R&D scientists.
