Explanation:

Let’s break it down:

- Option 1: Murder

That’s when someone acts with intention or knowledge that their act is so dangerous it’ll likely cause death. Hitting someone on the head with a lathi can show intention or knowledge, especially if the blows are aimed at vital parts. If there was clear intention to cause death, or such knowledge, this could fit.

- Option 2: Culpable homicide not amounting to murder

This is a step down from murder. Basically, if the intention was to cause bodily injury likely to cause death, but without the mental element of murder (like no intention to kill or knowledge it would most probably cause death), this one applies.

- Option 3: Grievous hurt

Here, the main goal is causing serious injury—not death. If death occurs, but there was no knowledge it was likely, this might fit, but six blows including one to the head? That suggests more than just grievous hurt.

- Option 4: Causing death by rash or negligent act

That’s mostly for accidents or reckless acts, not for situations where there’s intention to hurt.

Here’s what this really means:

Since A wanted to hurt B and delivered six hard blows (one to the head), and B died 20 days later because of it, we’re way past “grievous hurt.” The repeated blows and the fact one landed on a vital part (the head) make it more than just “hurt”—there’s enough intent or knowledge here to count as “culpable homicide not amounting to murder.”

So the answer:

Option 2: Culpable homicide not amounting to murder.
