B
ratio of cap h sub 0 to mu is equal to 2 point 7 ; ratio of cap h sub A to mu is not equal to 2 point 7
C
ratio of cap h sub 0 to mu is less than 2 point 7 ; ratio of cap h sub A to mu is greater than or equal to 2 point 3
D
ratio of cap h sub 0 to mu is greater than or equal to 2 point 7 ; ratio of cap h sub A to mu is less than 2 point 7
