Why is H_(3)PO_(2) a stronger reducing agent than H_(3PO_(3) ?

[SiF_(6)]^(2-) is known whereas [SiC_(6)]^(2-) not. The main reason is/are I Six large chloride ions cannot be accommodated around Si^(4+) due to limitation of its size. II. Interaction between lone pair of chloride ion and Si^(4+) is not very strong. Choose the correct option.
