Origin of life and evidences of evolution
Why this is asked: Miller and Urey's experiment specifically used a reducing atmosphere (CH4, NH3, H2, water vapour, no free O2) with an electric spark to generate amino acids — swap in an oxidising atmosphere and the option is wrong regardless of the rest of the setup. For evidence of evolution, the sharpest example pair is potato (a stem tuber) and sweet potato (a root tuber): same function, different origin, so they are analogous, not homologous.
