Secondary and tertiary roots are best described as which of the following?

Explanation:
Secondary and tertiary roots are branches of the root system. The main root is the primary root, and the roots that branch off from it are called lateral roots. As those lateral roots give rise to further branches, you get tertiary roots, which are still part of the same branching pattern. In short, both secondary and tertiary roots are lateral roots—roots that come off the main root and its branches. They are not roots arising from the stem, nor a fibrous root system, which describes a different arrangement.
