Answer:
Option A=> the act of failing to observe an agreement
Step-by-step explanation:
The underlined words in the question above “Unsatisfied with their explanation, Technic Inc. sued Androchon Ltd. for breach of contract.” is BREACH OF CONTRACT.
When two or more people make an agreement or when there is an agreement between two nations or an agreement between an employer and an employee we say that the two parties involved have a CONTRACT.
In the contract there is definitely going to be terms and conditions and when one of the parties break any of these terms and conditions we say that there is a BREACH OF CONTRACT.
Therefore, option A is the correct answer with the explanation in the paragraph above.
