Task: Answer the multiple choice question.
Query: Which drug has a -4.894\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CSc1nc(-c2ccccc2)nc(N2CCCC2)c1C(C)=O
b) CC(=O)c1ccc(Oc2cc(C)nc(-n3nc(C)cc3C)n2)cc1
c) CCNC(=O)NC(=O)CSc1cccc(C(F)(F)F)c1
Answer: a. CSc1nc(-c2ccccc2)nc(N2CCCC2)c1C(C)=O
