A base is any morphological form (root or stem) to which affixes can attach. A word “contains 2 bases” if it supplies two distinct attachment sites (two stems) that can independently take further affixes (for example a root and a derived stem). The table shows whether each word can take a derivational affix and whether it can also serve as a base for an inflectional affix; a word that supplies both is the one with two bases.

Step-by-step check of each option using the table:
1. friendly
- Derivational affix: un- + friendly → unfriendly (valid). This shows friendly functions as a base for a derivational prefix.
- Inflectional affix: friendli + -er → friendlier (valid; orthographic adjustment drops the final -y). This shows a (derived) stem friendli- serves as the base for the comparative -er.
Thus friendly provides two distinct bases (friend → friendly as a derived form, and friendli- as the stem for inflection), so it contains two bases.

2. caramel
- Derivational affix: caramel + -ize → caramelize (valid), so caramel is a base.
- Inflectional affix: *caramel + -er (marked impossible). There is no valid inflectional stem shown. Only one base is available.

3. nationalizable
- Derivational affix: nationalizabil + -ity → nationalizability (valid).
- Inflectional affix: *nationalizeable + -est (marked impossible). Only one usable stem is available in practice.

4. unlockable
- Derivational affix: unlockabil + -ity → unlockability (valid).
- Inflectional affix: *unlockable + -est (marked impossible). Although unlockable is morphologically ambiguous (un+lockable vs. unlock+able), the table shows it does not supply two distinct stems that take inflectional -est; only one base is productive here.

5. none of these is therefore incorrect because friendly does meet the criterion.

Why friendly is correct: it uniquely allows both a derivational prefix to attach (un-) and an inflectional comparative (-er) to attach to its appropriate stem, demonstrating two bases. Final answer: friendly.
