Breach refers to what?

• A. The basic unit of living things
• B. Breaking of a law, or of any obligation or contract
• C. A severe reaction to a drug
• D. A remedy for an overdose

Answer: (B)

Breach is a violation of a duty or contract. In practical terms, it happens when someone doesn’t do what they promised or fails to follow a law or agreement. For example, if a tenant doesn’t pay rent as agreed or a seller doesn’t deliver goods on time, that’s a breach, and the other party may seek remedies like damages. The other options relate to biology or medicine, not to breaking obligations: the basic unit of living things is a cell, a severe drug reaction is an adverse reaction, and a remedy for an overdose is an antidote or medical treatment. So breach specifically means breaking a commitment or rule.
