Dil mein dhadkan: Culpable Homicide Not Amounting to Murder vs. Culpable Homicide

Kya pata main samajh nahi paya, please help karein. Main aasha kar raha hoon ki aap mera problem solve kar sakte hain. Mera confusion ye hai: IPC Sect 304-A aur 304-B. Dono mein "culpable homicide" ka concept aata hai lekin dono alag-alag sharton par depend karte hain. Main samajh raha hoon ki 304-A mein shart ye hai ki vyakti ko saza niyamit ya ashuddh (imprisonment for life) hoga. Lekin 304-B mein "dowry death" ki situation mein kya hoga?
