a.Her injury does not constrain her at all; she still skis and plays basketball. b.The townspeople tried to constrain the elephant to roam freely. c.Every good chef knows how to constrain an egg before adding it to a recipe.
Answer: A
The word constrain has the idea of holding someone or something back.
If the options above are really those you need, then I agree with the person who said the correct usage of the word constrainis found in A) Her injury does not constrain her at all; she still skis and plays basketball. To constraint means to limit.
