Answer 1

In the word "unsustainable," the components "un-", "sustain," and "-able" are all examples of morphemes.

• "un-" is a prefix (an affix that comes before the root),
• "sustain" is the root (the main part of the word),
• "-able" is a suffix (an affix that comes after the root).

So, the correct response would be morphemes.
