The correct option is 92. According to the order of operations (BODMAS/PEMDAS), we first perform multiplication and division from left to right, and then addition and subtraction from left to right.\n1. Perform multiplication: $18 \times 5 = 90$.\n2. Perform division: $20 \div 4 = 5$.\n3. The expression becomes: $90 - 5 + 7$.\n4. Perform subtraction: $90 - 5 = 85$.\n5. Perform addition: $85 + 7 = 92$.\nIncorrect options arise from violating the order of operations, such as performing subtraction before division or multiplication.
