Answer: D

Explanation:

version = ">= 1.2.0, < 2.0.0"

A version constraint is a string literal containing one or more conditions, which are separated by commas.

Each condition consists of an operator and a version number.

Version numbers should be a series of numbers separated by periods (like 1.2.0), optionally with a suffix to indicate a beta release.

The following operators are valid:

= (or no operator): Allows only one exact version number. Cannot be combined with other conditions.

!=: Excludes an exact version number.

>, >=, <, <=: Comparisons against a specified version, allowing versions for which the comparison is true. "Greater-than" requests newer versions, and "less-than" requests older versions.

~>: Allows only the rightmost version component to increment. For example, to allow new patch releases within a specific minor release, use the full version number: ~> 1.0.4 will allow installation of 1.0.5 and 1.0.10 but not 1.1.0. This is usually called the pessimistic constraint operator.
