Given below are two statements:
Statement - I : The number of paramagnetic species among \( [CoF_{6}]^{3-} \), \( [TiF_{6}]^{3-} \), \( V_{2}O_{5} \) and \( [Fe(CN)_{6}]^{3-} \) is 3.
Statement - II : \( K_{4}[Fe(CN)_{6}] < K_{3}[Fe(CN)_{6}] < [Fe(H_{2}O)_{6}]SO_{4}.H_{2}O < [Fe(H_{2}O)_{6}]Cl_{3} \) is the correct order in terms of number of unpaired electron(s) in the complexes.
In the light of the above statements, choose the correct answer from the options given below.
- A Both statement - I and statement - II are true
- B Both statement - I and statement - II are false
- C Statement - I is true but statement - II is false
- D Statement - I is false but statement - II is true
