Evidence boundary

The source is Texas A&M CHEM 101, Spring 2001, Exam 3 Form A, question 21&22. All five options are retained in equivalent compact wording with unchanged values and order. The named species is formic acid, not an unspecified CH₂O₂ isomer; the diagram is schematic, and the answer evaluates the supplied options rather than reporting measurements.
