Select the correct option w.r.t. increasing order of respiratory quotient of various substrates.
Fats < Protein < Oxalic acid
Malic acid < Oxalic acid < Fat
Protein < Fat < Malic acid
Oxalic acid < Protein < Malic acid
Respiratory quotient (RQ) of Fats → 0.7, Protein → 0.9, Organic acids >1 ( E.g., Malic acid → 1.33 and oxalic acid → 4.0).
