For a Parson's reaction turbine, if α_{1} and α_{2} are fixed blade angles at inlet and exit respectively and β_{1} and β_{2} are the moving blade angles at entrance and exit respectively, then

[A].

α_{1} = α_{2} and β_{1} = β_{2}

[B].

α_{1} = β_{1} and α_{2} = β_{2}

[C].

α_{1} < β_{1} and α_{2} > β_{2}

[D].

α_{1} = β_{2} and β_{1} = α_{2}
