Problem statement: Answer the multiple choice question.
Query: Which compound has a 8.740\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. O=C(NC1CCCC1)C1CCC(CNS(=O)(=O)c2cccs2)CC1
b. O=C(CCl)N=c1sccn1Cc1ccccc1Cl
c. O=c1[nH]c(Cc2ccccc2)nc2c1oc1ccccc12
d. O=C(/C=C/c1ccc(F)cc1)N1CCCc2ccccc21
Answer: c. O=c1[nH]c(Cc2ccccc2)nc2c1oc1ccccc12
