Final answer:
In a situation where a tenant borrows money from a bank to improve an apartment by adding a bathroom, the landlord does not directly fit into the categories of delegator, delegatee, or obligor, but could theoretically be considered the obligee since they may benefit indirectly from the apartment's improvement.
Step-by-step explanation:
In the context described where a tenant borrows money from a bank to add a bathroom to her apartment, and considering basic contract principles, the different parties in a contract situation are as follows: The delegator is an original party who delegates their duties to another party, the delegatee is the party who is delegated duties by the delegator, the obligor is the party who has an obligation or a duty under the contract, and the obligee is the party that is entitled to receive the benefit or performance from the obligor.
In this particular scenario, the landlord would not be the delegator, the delegatee, nor the obligor. The landlord's role is not directly related to the loan from the bank. Given the choices provided and typical contractual relationships, the landlord does not fit neatly into any of these roles since the landlord is not a party to the loan agreement between the tenant and the bank.
