A: It will decrease by a factor of 1/4

#### Explanation:

Think of it like this:

Pretend $\left[B\right] = 1$

${\left[B\right]}^{2} = \left[B\right] \left[B\right]$ so ${\left[1\right]}^{2} = \left[1\right] \left[1\right] = 1$

Now half B:

${\left[0.5\right]}^{2} = \left[0.5\right] \left[0.5\right] = 0.25$

Half of a half is a quarter
