According to the text, which of the following is NOT an element common to organic molecules identified by Miller or a major element uniformly found in life?

  • A: Hydrogen (H)
  • B: Carbon (C)
  • C: Oxygen (O)
  • D: Iron (Fe)

Explanation

The text lists C, H, O, N, S, and P as major elements of life. Miller's experiment identified organic molecules containing carbon, hydrogen, nitrogen in NH3 and HCN , and oxygen in CH2O . Iron Fe is not mentioned in the context of Miller's products or as a major, uniformly found element of life in this passage.
