We can set up a proportion to solve this problem. Let's represent the amount of baking soda with "x".
We have the ratio of baking soda to flour as 2 tsp/6 lbs. = x tsp/9 lbs.
Cross-multiplying, we get 6x = 2 * 9.
Simplifying, we have 6x = 18.
Dividing both sides by 6, we find that x = 3.
Therefore, Lisa should add 3 tsp of baking soda to 9 lbs. of flour.
So, the answer is A: 3 tsp.
