IS THE RATE GIVEN IN $\%$ OR DECIMALS? How to solve this? Consider the following two projects:

Assume that projects A and $B$ are mutually exclusive. The correct investment decision and the best rationale for that

decision is to

A$.$ invest in project $A,$ since $BBIR{R}_B>IR{R}_{A}ANP{V}_A>0B{N}_B{V}_B>N_{A}NP{V}_B$

$B.$ invest $in$ project $B,$ since $IR{R}_B>IR{R}_A$

$C.$ invest $in$ project $A,$ since $NP{V}_A>0$

$D.$ invest $in$ project $B,$ since $N_B{V}_B>N_A$
