Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.256\% 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(CNS(=O)(=O)c1cccc(Cl)c1)Nc1ccc(-c2nc3ccccc3s2)cc1
b COCCCNc1nc2nonc2nc1N(C)CC1CCCN1C
c O=C(NCc1ccccc1Cl)c1ccncc1
d CCCN(CCC)CCCNC(=O)c1cc2c(=O)n(CC)c3ccccc3c2s1
Answer: c. O=C(NCc1ccccc1Cl)c1ccncc1
