Task: Answer the multiple choice question.
Query: Which drug has a -21.069\% 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, or d without using any other words.
Options:
[a] Cc1ccc(C2(c3noc(CN4CCC(c5ccncc5)CC4)n3)CCCC2)cc1
[b] CC(C)CC(=O)N1CCN(S(=O)(=O)c2ccc3ccccc3c2)CC1
[c] O=C(/C=C/c1ccc(Cl)cc1)NCCCN1CCOCC1
[d] CCOC(=O)N1CCN(C(=O)CSCc2ccccc2)CC1
Answer: c. O=C(/C=C/c1ccc(Cl)cc1)NCCCN1CCOCC1
