hi, Required Proof : ab+c>a+bc => (since integers) 2c>2b (we are not multiplying with a negative sign hence no sign change) => c>b Now to prove this Statement 1 : B is negative We dont know anything about C so Insufficient Statement 2 : C is positive We dont know anything about B so Insufficient Combine : C positive & B Negative Hence C > B Sufficient Hope this helps

HERE the question is asking for if B<C or not.. Clearly C is sufficient
