The material with the best combination of large thermal conductivity and small thermal expansion is tungsten.

Here's why:

a. 1025 Steel: Steel has a moderate thermal conductivity and a relatively large thermal expansion.

b. Fused silica (SiO2): Silica has a very low thermal conductivity and a very small thermal expansion.

c. Gold: Gold has a high thermal conductivity but also a high thermal expansion.

d. Tungsten: Tungsten has a high thermal conductivity and a very small thermal expansion, making it the best choice among the given options.
