Directions: A clock is so placed that at 12 noon its minute hand points towards West. The mathematical operators have been placed at the minute hand position at particular time given below: '' at half past six '×' at twenty minutes past seven '+' at quarter past eight '-' at nine o'clock '÷' at five minutes to ten Which is the correct mathematical expression based on above information?

Using the standard clockwise directional method, the minute hand pointing West at 12:00 noon places the hour hand pointing North. At 6:30, the minute hand points East, so the subtraction operator is placed at E. At 7:20, the minute hand points Southwest, so the multiplication operator is placed at SW. At 8:15, the minute hand points South, placing the addition operator at S. The correct representation of the operators in the formula uses E for subtraction and SW for multiplication. Option A correctly displays these exact directional mappings.
