Answer: B, If you share your goals, you are more likely to achieve them.
We know sharing goals can be helpful to everyone, one of the main reasons people share goals is so that they can get the motivation to carry on doing their work. For example, If you and a friend had a goal of going to the gym 3 times a week you would feel responsible if you told your friend that you wouldn't be able to complete the goal this week. Which would make you feel bad for your friend who wants to complete the goal. It also helps with motivation if your friend doesn't want to go then you encourage them and make sure they remember the goal.
Answer choice A, would not make much sense since you are doing the goal together, and + this is a school question and they wouldn't encourage ego. Answer choice C, could be a result of sharing goals with others but doesn't suit the question as much as B. Answer choice D, does apply to the question at all people could end up liking you more but it could also end up the other way around.
Our answer is without a doubt B
Enjoy!
