Answer Details

The element that is most likely to be deficient in the mother's diet during pregnancy and cause weak and crooked bones in the child is calcium and phosphorus. Calcium is an important element for bone formation and its deficiency can lead to a condition called rickets which results in weak and deformed bones. Phosphorus is also necessary for proper bone growth and development. Deficiency in both these elements during pregnancy can result in skeletal abnormalities in the developing fetus. Therefore, the most appropriate answer would be (c) Calcium and phosphorus.
