Original height=10 feet

Height after first bounce: (10 feet) * 90% = (10 feet) * 90/100=9 feet

Height after second bounce: (9 feet) * 90% = (9 feet) * 90/100=8.1 feet

Height after third bounce: (8.1 feet) * 90% = (8.1 feet) * 90/100=7.29 feet = 7.3 feet

Height after fourth bounce: (7.29 feet) * 90% = (7.29 feet) * 90/100=6.561 feet=6.6 feet

Answer: Option B) 9, 8.1, 7.3, 6.6, ...
