It would be really helpful if you told us your case or the facts of the case. You should also tell us who the alleged offender is so that we can tell you the kind of punishment he/she might have to deal with.
Section 376 of IPC provies punishment for the offence of Rape:
It states that,
Whoever, except in the cases provided for in sub-section (2), commits rape, shall be punished with rigorous imprisonment of either descripttion for a term which
shall not be less than seven years, but which may extend to imprisonment for life, and shall also be liable to fine.
While Section 304 B of IPC deals with the offence of dowry death and the punishment for it.
It states that,
(1) Where the death of a woman is caused by any burns or bodily injury or occurs otherwise than under normal circumstances within seven years of her marriage and it is shown that soon before her death she was subjected to cruelty or harassment by her husband or any relative of her husband for, or in connection with, any demand for dowry, such death shall be called “dowry death”, and such husband or relative shall be deemed to have caused her death. Explanation.—For the purpose of this sub-section, “dowry” shall have the same meaning as in section 2 of the Dowry Prohibition Act, 1961 (28 of 1961).
(2) Whoever commits dowry death shall be punished with imprisonment for a term which shall not be less than seven years but which may extend to imprisonment for life.]
