Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.538% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a. COc1ccc(CCNC(=O)c2ccc(S(=O)(=O)N3CCCCC3)cc2)cc1
b. Cc1ccc(NC(=O)CCC(=O)NNC(=O)NC2CCCCC2)c(C)c1
c. CC1=Nc2ccccc2/C1=C\c1nc(-c2ccccc2)oc1O
d. O=C(O)c1ccc(CSc2nnnn2-c2ccc(F)cc2)cc1
e. CCCn1c(SCc2ccc(Cl)cc2)nc2c1c(=O)[nH]c(=O)n2C
Answer: c. CC1=Nc2ccccc2/C1=C\c1nc(-c2ccccc2)oc1O
