Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.909% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1ccc(S(=O)(=O)n2cnc3ccccc32)c(C)c1
b. Cc1ccc(C)c(-c2cc(C(=O)NNC(=S)NCC(C)C)c3ccccc3n2)c1
c. CCc1ccccc1N/N=C(/C)c1c(O)cc(C)oc1=O
d. O=C(N/N=C\c1cc(Br)c(Br)o1)c1cncc(Br)c1
Answer: c. CCc1ccccc1N/N=C(/C)c1c(O)cc(C)oc1=O
