why not A ? |

A is wrong: how could it produce more precise... |

A sampling distribution of a statistic is descriptive, it does not produce anything. |

A is the definition for stratified random sampling |

What your confused about is the Stratified is more precise then Simple random sampling...less variability when the estimates produced. |
