Final answer:
The lender can refuse to allow an assumption.
Step-by-step explanation:
In this case, the correct statement is option 3) The lender can refuse to allow an assumption.
An alienation clause in a loan indicates that the lender has the right to refuse or restrict the transfer of the title to another party. This means that the lender can prevent the buyer from assuming the loan if they choose to do so.
However, it's important to note that the lender may have specific conditions or criteria for allowing an assumption, such as the buyer qualifying for the loan. So, option 4) The lender may NOT require that the buyer qualify to assume the loan is incorrect.
