Explanation:

Let’s break down the options one by one:

- By half blood: If two people share the same father but have different mothers, they’re half-blood siblings. In Islam, marrying a half-blood sister is not allowed.

- By half uterine blood: This means same mother, different fathers. Same rule—prohibited to marry.

- A consanguine: Consanguinity means blood relationship. A “consanguine sister” is also a sister by blood—same father, possibly different mothers.

- All of the above : Here’s the thing—all three options describe sisters you can’t marry under Muslim law.

What this really means: it doesn’t matter if the sister is from the same mom, the same dad, or either—marriage is off the table for all. So, the correct option is All of the above.
