B, A, B

Step-by-step explanation:

Let's find the z-score for both companies using the formula: $z=\dfrac{x-\mu}{\sigma}$

Company A: $z=\dfrac{43-38.2}{1.7}=\large\boxed{2.8}$

Company B: $z=\dfrac{43-36.9}{2.4}=\large\boxed{2.5}$

The z-score from Company B is closer to 0 than the z-score of Company A so it it more likely that a package of 43 lozenges is produced by Company B
