Show answerHide answer

Correct answer: (C) Both (a) and (b)(a) और (b) दोनों

Explanation

Non-metals generally do not react with water, and they do not react with dilute acids to release hydrogen because they cannot give electrons to H⁺ ions. Both statements are correct.अधातुएँ सामान्यतः जल से अभिक्रिया नहीं करतीं, और तनु अम्लों से अभिक्रिया करके हाइड्रोजन मुक्त नहीं करतीं क्योंकि वे H⁺ आयनों को इलेक्ट्रॉन नहीं दे सकतीं। दोनों कथन सही हैं।
