**Rotational Stability in Newman Projections**Consider rotation about the indicated bond in the molecule below. Which Newman Projection formula best represents the most stable conformer of the molecule with respect to rotation about the indicated bond? [As noted below: there is no steric strain between -H and -Et that have a gauche, staggered relationship]**Diagrams:**- There is a molecular diagram at the top showing a compound with a central carbon atom bonded to a bromine, a hydrogen, and an ethyl group (CH₂CH₃).- Below are three Newman projection diagrams labeled I, II, and III: - **I**: Shows bromine and an ethyl group in a staggered formation with hydrogen atoms. - **II**: Shows bromine and hydrogen in a staggered formation with an ethyl group and other hydrogen atoms. - **III**: Shows the ethyl group and hydrogen staggered, with bromine positioned next to hydrogen atoms.- A note box to the right emphasizes that there is "no steric strain" when CH₃CH₂ and H are in this position.**Select one:**- A. I- B. II- C. III- D. All conformers have identical energies.The diagram in the note suggests that the absence of steric strain occurs when larger groups are staggered.
