Remember that an adjective is a word that describes the qualities or states of being nouns, in other words, they modify nouns. In this case the only adjective I found is <em>small</em>, it describes the noun <em>pots</em>.
Next to <em>small </em>we can find the word <em>very</em>, this is an adverb. An adverb is a word that modifies or describes a verb, and adjective, or another adverb. In this case it is modifying the adjective <em>small</em>.
" C. incur" is the proper word here. "Incur" means to "get" or "become subject to" something, usually with the connotation that this happened as a result of one's own behavior.
