What is the correct answer for CBSE10?

The correct answer is B. Hydrogen-ion concentration is inversely proportional to pH. A lower pH means a higher H⁺ concentration. So, to arrange in increasing order of H⁺ concentration, we need to arrange in decreasing order of pH: C (pH 11), E (pH 9), D (pH 7), A (pH 4), B (pH 1). Thus, C < E < D < A < B.
