If \( A = \frac{9}{16} \div \frac{25}{36} \), \( B = 9 \div [(16 \div 25) \div 36] \), \( C = [9 \div (16 \div 25)] \div 36 \), \( D = (9 \div 16) \div (25 \div 36) \), then which of the following is true?
A and D are equal.
By simplifying each given expression step by step, it is determined that A and D are equal.
