Which prefix represents 10^12 as listed in the material?

Explanation:
In the SI prefix system, each prefix represents a specific power of ten. For 10^12, the standard prefix is tera-, symbol T. Tera- is used to denote a trillion in scientific contexts. The term “tetra” isn’t a standard SI prefix for powers of ten; it comes from Greek for four and isn’t used in this system. The other options map to smaller scales: deka- is 10^1, kilo- is 10^3, and mega- is 10^6. So the correct prefix for 10^12 is tera-.
