A
103 MPH TAS, 6.3 GPH.
B
105 MPH TAS, 6.2 GPH.✓ Correct Answer
C
105 MPH TAS, 6.6 GPH.
Explanation
In the Figure 11 table, the 7,500-foot block shows 52 percent BHP at 2,300 RPM, giving 105 MPH true airspeed and 6.2 gallons per hour. The 103 MPH and 6.3 GPH values belong to the 2,500-foot row at 52 percent, and 6.6 GPH does not appear for 52 percent power.
