Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.023\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] O=C(CSc1n[nH]c(=O)[nH]c1=O)Nc1ccc(C(=O)O)cc1
[b] O=C(NCCCN1CCOCC1)c1ccc2nc(Cc3ccccc3F)oc2c1
[c] CCOC(=O)c1c(N)sc(C(=O)N2CCOCC2)c1C
[d] CC1=C(C(=O)Nc2ccccc2Cl)C(c2ccc(N(C)C)cc2)NC(=O)N1
Answer: c. CCOC(=O)c1c(N)sc(C(=O)N2CCOCC2)c1C
