Why there is no interference pattern observed when two coherent sources are placed far apart?

An electric drum is enclosed inside a specially designed closed glass chamber, as shown in the given figure. On switching the current, the hammer repeatedly strikes the membrane of the drum. Hence, the membrane vibrates and produces sound that can be heard at a distance. Now, the chamber is evacuated by closing the switch of the vacuum pump. As the chamber is evacuated, the

  • A double-slit interference experiment is set up in a chamber that can be completely evacuted. With monochromatic light, an interference pattern is observed when the container is open to air. As the container is evacuated, a careful observer will note that the interference fringes

    do not change at all
    B
    move slightly farther apart
    C
    move slightly closer together
    D
    disappear completely
