How should the nurse best interpret the role of genetics in the client's observation that despite having overweight parents, they have never had problems maintaining a healthy weight?
A) Genetics have a strong influence on weight, so the client's ability to maintain a healthy weight is likely due to genetic factors.
B) Genetics have no influence on weight, so the client's observation is purely coincidental.
C) Genetics can influence weight, but environmental and lifestyle factors also play a significant role.
D) Genetics solely determine weight, so the client's observation is not relevant.
