Here's why:
* -ence is a common suffix used to form nouns, often from verbs or adjectives. Examples: "dependence," "difference," "existence."
The other options are not typical noun suffixes:
* -ible indicates something is capable of being done (adjective: "flexible").
* -ive indicates something that does or relates to something (adjective: "attractive").
* -full indicates fullness or abundance (adjective: "joyful").
