The SI prefix for 10^18 is which of the following?

Explanation:
Powers of ten are encoded with SI prefixes. Pico, nano, and micro represent tiny quantities (10^-12, 10^-9, and 10^-6, respectively), while exa represents a very large quantity (10^18). So for 10^18, the matching prefix is exa. A familiar example is 1 exabyte = 10^18 bytes, which helps visualize this large scale. The smaller prefixes describe much smaller amounts, which is why they don’t fit 10^18.
