Please explain why the answer is D and not A, B or C. I'm trying to understand it. How would we do evidential reason and intercausal reasoning on this network and why?

9. Consider the probabilistic graphical model in Figure 12 and indicate which of the following statements are correct. A. We can do evidential reasoning by computing P(l1) and P(l1i0,d0) B. We can do causal reasoning by computing P(i1) and P(i1l0,g0) C. We can do intercausal reasoning by computing P(i1) and P(i1l0,g0) D. We can do causal reasoning by computing P(l1) and P(l1d0) E. None of the above is correct
