To have capacity to contract means that:
d) the party can understand the contract
The capacity to contract refers to whether a person is legally competent to enter into a binding agreement. The key requirement is that the person can understand the nature and consequences of the contract. Options a, b, and c do not fully capture the meaning of contractual capacity.
Unfair trade practices include:
d) all of the above
False endorsements, false advertising, and misleading price information are all examples of unfair trade practices that can be prohibited under consumer protection laws. So option d "all of the above" is the correct answer, as it encompasses the full range of unfair trade practices. Options a, b, and c are incomplete because they each only list one type of unfair trade practice, rather than including all of them.
In summary:
To have capacity to contract means the party can understand the contract.
Unfair trade practices include false endorsements, false advertising, and misleading price information - so "all of the above" is the correct option.
