You are comparing two mutually exclusive projects. The crossover point is $9\mathrm{.}3\%.$ You have determined that you should accept project Alpha if the required return is $10\mathrm{.}1\%.$ This implies you should:

Be indifferent to the projects at any discount rate above $10\mathrm{.}1\%.$

Accept Project Alpha if the required return exceeds the crossover rate.

Accept Project Beta if the required return is less than $10\mathrm{.}1\%.$

Always accept Project Alpha.

Accept Project Beta only when the required return is equal to the crossover rate.
