Answer:Ester is liable for breaching her duty of loyalty to the LLC with Yi, Maria and Enrique.
Explanation:
Loyalty refers to the state of remaining true to the business without committing things that will gain only you apart from your partners.
If she is now starting the company secretly without her partner's knowledge she is no longer looking at the best interest of the business but of her own needs individually and is not being loyal to the company that they started all together.
