Hi, Bli,
Good question. Let's step through the process for questions like these. When you are asked to parallel something in the passage, start by reading the relevant portion in detail and then describing the scenario, abstractly. The key is to hit the right amount of detail: too much detail and you are dealing with too many particulars, too little detail/too broad and several answers likely work.
In this case, a prephrase might look something like the following:
- Efforts to create something new by blending parts of old items leads instead to interest in the old items and lack of interest in the new creation.
Note that here that while "unintended consequences" might be a good parallel with (A), the rest of (A) doesn't match.
In contract, this prephrase syncs up well with the scenario described in the credited response, (B). "Seed-research firms" parallels with Marsalis in this construction. The qualitative difference between Marsalis, a person, and a seed-research firm, a company, does not detract sufficiently to prevent this answer from being the closest possible parallel among the answer choices.
