Let the two numbers be x and y
xy = 12= 144 ⇒ x = 144/y
x : y = y : 96
x × 96 = y2
144/y × 96 = y2
y3 = 144 × 96
⇒ y = 24
x = 144/24 = 6

Mean Proportion:
The mean proportion between two numbers is the square root of their product. Let's assume the two numbers as x and y.

Mean Proportion:
The mean proportion between x and y can be represented as √(x * y).

Third Proportion:
The third proportion is the product of the mean proportion and the second number. In this case, the third proportion is 96.

Equation:
We can set up the following equation based on the given information:
√(x * y) = 12
12y = 96

Simplifying the Equation:
From the second equation, we can solve for y:
y = 96/12
y = 8

Substituting this value of y into the first equation:
√(x * 8) = 12
√8x = 12
Squaring both sides:
8x = 12^2
8x = 144

Solving for x:
x = 144/8
x = 18

Conclusion:
The two numbers are 6 and 24, which corresponds to option B.
