C Correct answer
Explanation

Yes, all are correct. Rubredoxin is a small iron-sulphur protein found in various sulphur-metabolising bacteria. Rieske proteins are iron-sulphur protein components of cytochrome bc1 complexes and cytochrome b6f complexes, which were first discovered and isolated by John S. Rieske and co-workers in 1964. Aconitase is an iron-sulphur protein that catalyses the interconversion of citrate and isocitrate
