Maria is the sheriff of Narez, Texas. Oscar robs a Narez gas station and a $500 reward is offered for his capture.

When, later, Maria finds and arrests him, with respect to the reward, she can:

a. collect it.

b. not collect it because she had a preexisting duty to capture Oscar.

c. not collect it because it is not legally sufficient consideration.

d. not collect it because it would be unconscionable.

When, later, Maria finds and arrests him, with respect to the reward, she can:

b. not collect it because she had a preexisting duty to capture Oscar.

Explanation:

The reason is that preexisting duty allows Maria to arrest Oscar but not to collect the reward as arresting Oscar is her prior duty. So, the option b is correct. The option a is not correct as she can't collect it due to her preexisting duty. The option c is not correct as it is legally sufficient consideration due to preexisting duty rule. The option d is incorrect as collecting reward is not unethical.
