How was the paper guys ?
@mounikamouni24_h944 it will be chenab.Question basically has two parts.3 other rivers meeting in main river and which joins the indus directly.So sutlej can be negated from this as ravi and jhelum meet chenab, not sutlej.And in chenab all other three rivers meet.Don't just look at one part of question I.e. which meets indus directly.
For this question, only thing can be said that it is very poorly worded and now it is upto UPSC , whether Chenab or Sutlej. And this one question may shatter the dreams of many as 2.66 marks are very important in this absurdly set paper checking random facts.
- During its (Satluj) onward journey it receives the collective drainage of the Ravi, Chenab and Jhelum rivers. It joins the Indus a few kilometres above Mithankot.

As regarding the question about " State", i still have doubt whether all states need to be Sovereign?As there are some Non sovereign states also if we search.you r spot on,I strongly believe its b but none would accept it as coaching keys claim its a..Just wait for the result.it does not matter after that.
As per montveido convention state has 4 characteristics: People, Territory, Govt and Sovereignty.
