Read the following statements regarding enzyme catalysis
(i) Enzyme catalysis is highly specific in nature.
(ii) Enzyme catalysis to work effectively requires optimum temperature \( (298-310 \mathrm{~K}) \) and optimum \( \mathrm{pH}(3-5) \)
(iii) Metal ions like \( \mathrm{Na}^{+}, \mathrm{Mn}^{2+}, \mathrm{Co}^{2+}, \mathrm{Cu}^{2+} \) etc. increases the activity of enzymes.
(iv) Catalyst used in Ostwald's process is platinised asbestos at \( 673 \mathrm{~K} \).
(v) Catalyst used in contact process is platinised asbestos or \( \mathrm{V}_{2} \mathrm{O}_{5} \) at \( 673-723 \mathrm{~K} \).
Which of the following is the correct coding for the above statements?
(a) FTFTF
(b) TFTFT
(c) TTFFF
