Final answer:
In the analogy, 'elucidate' is to 'nebulous' as 'contend' is to 'obscure.' 'Elucidate' means to explain something unclear or nebulous, and 'contend' means to argue against something, often something obscure.
Step-by-step explanation:
The analogy in question goes as follows: elucidate is to nebulous as contend is to _____. The word 'elucidate' means to make something clear or to explain it, usually something that was previously hard to understand or nebulous, which means vague or unclear. Therefore, in the analogy, you are looking for a word that pairs with 'contend' in a similar manner.
'Contend' means to argue or struggle in opposition. When we consider the words given in the options, we need to find a word that is a state or condition typically opposed by 'contend.' The correct answer is (c) obscure because 'obscure' may describe a situation or condition that one would contend or argue against much like one would elucidate or make clear something that is nebulous.
