Correct answer:  18 + 6 × 24 - 4 ÷ 64 = 50

Explanation:

After interchanging the operators, we evaluate each option:

OPTION A: \(18- 6 \times 24 \div 4 + 64 = 46 \neq 50\)

OPTION B: \(18 \times 6 - 24 \div 4 + 64 = 166 \neq 50\)

OPTION C: \(18 \times 6 + 24 \div 4 - 64 = 50\)

OPTION D: \(18 \div 6 + 24 \times 4 - 64 = 35 \neq 50\)

Final Answer: \(\boxed{C}\)
