The Correct Option is D

Solution and Explanation

Step 1: Balance the reaction for sulfur \(S_8\), ensuring that the atoms on both sides are equal for all elements. 
Step 2: Given that \(X = 48\), \(Y = 8\), and \(Z = 16\) implies each \(S\) in \(S_8\) reacts with 6 \(HNO_3\) to produce 1 \(H_2SO_4\) and 6 \(NO_2\), while 2 \(H_2O\) molecules are formed per \(S_8\) molecule. 
Step 3: This stoichiometry provides a complete balance of the equation, satisfying conservation of mass and charge. 
Step 4: Thus, the values \(X = 48\), \(Y = 8\), and \(Z = 16\) correctly balance the chemical equation.
