Answer: option B. weak core muscles.
Core muscles are fundamental to keep posture, resist forces without changing your position and resist forces that change your plane of motion.
So, it is inferred that weakness of core muscles would cause poor balance. Disciplines like yoga and pilates focus on exercises to strengthen core muscles to gain good balance.
Having good balance is important to avoid injuries due to falls, to be more active and able to perform daily activities: walk, climb stairs, play with children, play sports, hiking, among others.
