<option>
<option> is a General Operator
component that defines a selection element within a <select> block.
If only <math> type components are to be selected, the <option>
component can be excluded and selection items can simply be listed with a space between list items.
However, if multiple types or complex selections are required, the <option> component is necessary.
When varying component types are used as options, such as
a <text>, <function>,
or <number>, these tags are nested within the <option> tag.

Example: Retrieving <option> selections with multiple elements
It is possible to group several components for selection within a single <option> component.
In order to reference a specific component within a selected <option>, use array notation.
The first index of the array notation refers to the selected <option> component, and the
second index refers to the specific component within the <option> component.

Attribute Example: selectWeight
The <option> component is used with the selectWeight attribute. This attribute takes any numerical value and defaults to 1. In the case below, the red option is twice as likely to be selected during recursive selections (note that the <select> component has attribute specification withReplacement="true") as the green or yellow options.
