b. of Jewish faith
Explanation:
Sat shiva is a Jewsih ritual in which the death of a very close relative like grandmother, in this case, is mourned. The mourning period is of seven days as the word 'shiva' is Hebrew for seven hence meaning sitting for seven days. All the mirrors in the house are covered to avoid any distractions from mourning and is considered part of sat shiva ritual. Hence, Dana is most likely of Jewish faith.
