Go through the following statements.
(i) In proteins, right handed and left handed helices are observed
(ii) In B-DNA, at each step of ascent, the strand turns `36^(@)`.
(iii) Living process is a steady - state in equilibrium.
(iv) The rate of reaction doubles or decreas- es by half for every `10^(@)` C change in ei- ther direction.

Options

A. (i), (iii) & (iv)
B. (ii) & (iv)
C. (i) & (iv)
D. All are correct
