Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.698\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOC(=O)c1sc(NC(=O)CN2C(=O)NC3(CC(C)CC(C)(C)C3)C2=O)cc1C
b: Cc1nc(-c2ccc(Cl)cc2)sc1C(=O)O
c: c1ccc(-n2cnc3cc(NCc4cccs4)ccc32)cc1
d: O=C(NC1(C(=O)NC2CCCCC2)CCCCC1)c1ccccn1
e: O=C(NCCCc1ccc(F)cc1)C1CCC(=O)N(CC2CCCCC2)C1
Answer: c. c1ccc(-n2cnc3cc(NCc4cccs4)ccc32)cc1
