The best way to keep our bones strong within the options that were provided would be (B) Preform muscle strengthening exercises regularly.
From these options we can definitely use the "process of elimination". Option (C) would be thrown out immediately, as vitamin D is an absolute necessity for bone health because Vitamin D actually helps absorb the calcium into our system. So we'd definitely want to get a lot of natural Vitamin D by the sun (but remember your sun block!).
Secondly, option (D) would be thrown out, also. You want to consume dairy products because that's where your natural calcium comes from. As previously established, our bones REQUIRE calcium. Without the calcium, our bones will become brittle.
Lastly, option (A) would help mostly your muscles by stretching. Stretching daily is very important to your physical health and your posture and a lot of other benefits but it's not really related to your bone health.
Thus, the only option that would fit would be, option (B). strength training is extremely beneficial to our bones!
Invest in a healthy cookbook, you can try new dishes and find some that you like. Research plants that grow well in your climate and plant some fruits/veggies. Buy fresh ingredients. Make a list of healthy foods that you enjoy. Try cooking things different ways because anything can taste good if cooked nicely. (put oil in a pan and cook brussel sprouts until they are a little soft, season with salt and pepper.) Shop at Trader Joe's and Lucky's Market if possible. They have cheap and healthy products. I strongly recommend Lucky Market.

If possible, have someone reference her emergency medical forms filed with the school so you can see who else to contact. If she has an inhaler (usually albuterol) administer that as directed, and get her to a hospital if the other methods dont present a solution.
