Two absolute scales \( A \) and \( B \) have triple points of water defined to be \( 400 \mathrm{~A} \) and \( 300 \mathrm{~B} \). The relation between \( T_{A} \) and \( T_{B} \) is (triple point of water is \( 273.16 \mathrm{~K} \) temperature and \( 6.11 \times 10^{-3} \mathrm{~atm} \) pressure at which water co-exists in gas, liquid and solid states)
(a) \( T_{A}=\frac{4}{3} T_{B} \)
(b) \( T_{B}=\frac{4}{7} T_{A} \)
(c) \( T_{A}=\frac{4}{7} T_{B} \)
(d) \( T_{B}=T_{A} \)
