Most of the children in that camp program are recycling their milk cartons which best identifies the antecedent of the underlined personal pronoun (which is their) a that b program c most d camp

b) Program

Explanation:

Program is the correct answer since the word camp is an adjective saying what kind of program the kids are in.

i think the correct answer would be adjustments in life roles.  this causes for one to adjust or change totally his/her career or lifestyle since the present is not beneficial to the life role he is at. for instance, you became a mother you would of course stop going to malls and enjoying life outside. you would be staying at home taking care of your child.
