Remember that we need at least one person from IK, LO and GL in order to go F, W and T.
A is wrong because neither L nor O is on the crew. There is no one to do W.
B is CORRECT. Here’s who could do the tasks:
F: K
W: L
T: G
S: H
P: H
S and P could be done on different days, by H.
C and D are wrong because neither G nor L works. N one can do T.
E is wrong because neither I nor K works. No one can do F.
