blue dwarf stars have a relatively small solar radius and a relatively high temperature
red dwarf stars have a relatively small solar radius and a relatively high temperature
red giant stars have a relatively small solar radius and a relatively high temperature
red giant stars have a relatively large solar radius and a relatively low temperature
red giant stars have a relatively large solar radius and a relatively high temperature

Explanation:

Blue dwarfs are small, hot stars. Red dwarfs are small but cool, not hot. Red giants are large, evolved stars with low surface temperatures (their red color indicates lower heat).

Answer:

Blue dwarf stars have a relatively small solar radius and a relatively high temperature
Red giant stars have a relatively large solar radius and a relatively low temperature
