I know Im only supposed to ask one question but Im running out amd just need help with these last 4 so if you could explain them Id really appreciate it. thanks!

In case the minimum required return for these investments is 15 % , what is the best project for R+C? a) Project A b) Project B c) Both projects are equally good for R+C d) We do not have enough information to answer this question 12. In case the opportunity cost of capital for these investments is 7 %, what is the best project for R+C? a) Project A b) Project B c) Both projects are equally good for R+C d) We do not have enough information to answer this question. 13. A Fisher's rate (crossover rate) of 9.39% represents: a) The discount rate that makes NPVA=NPVB b) The IRR of the incremental investment B-A c) The discount rate that makes projects A and B equally valuable for R+A d) All of the above. 14. Financial break-even analysis: a) Examines how sensitive a particular NPV calculation is to changes in underlying assumptions b) Deals with risk that comes from the project opportunity cost of capital. c) Plots the NPV as a function of the discount rate. d) Studies the minimum number of units the company has to sell to get positive NPV
