Explanation

Option B is the wrong statement because Apache Solr's wt (writer type) parameter does not support HTML as a response format. Solr's supported output formats include XML (the default), JSON, CSV, Python, Ruby, PHP, and binary formats like JavaBin - HTML is simply not among them.

Option A is a correct statement (not wrong), since both CSV and JSON are genuinely supported by the wt parameter, making it a valid distractor. Option C is also a correct statement - CSV, JSON, and XML are all legitimate Solr response formats, so it cannot be the wrong answer.

Memory tip: Think of Solr as a data API, not a web renderer - it outputs raw data formats (XML, JSON, CSV) for programmatic consumption, never presentation-layer formats like HTML. If you see HTML listed among Solr wt options, that's your red flag.
