When Beulah suffered a $$600,000$ liability loss, she discovered that her policy had a $$300,000$ limit rather than the $$500,000$ limit shown on the certificate of insurance $($COI$)$ her agent had provided to Beulah's client. The contract between Beulah and her client required Beulah to carry insurance with a $$500,000$ limit$.$ Beulah sues her agent to recover the $$200,000$ difference between the $$300,000$ amount covered by her policy and the $$500,000$ limit shown in the COI. Beulah's lawsuit is most likely to be successful if it is made on the basis of

a$.$ contract law.

b$.$ fraud laws.

c$.$ negligence.

d$.$ strict liability.
