Task: Answer the multiple-choice question.
Query: Which drug exhibits a 9.318\% 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 CC(=O)Cc1nsc(NC(=O)c2c(-c3ccccc3Cl)noc2C)n1
b Cc1ccc(NC(=O)CN(C)S(=O)(=O)c2ccc3c(c2)n(C)c(=O)c(=O)n3C)c(C)c1
c O=C(CCNC(=O)c1ccc(Cl)cc1)NCCCN1CCOCC1
d COC(=O)C1=C(C(C)=O)C(c2ccc(C(=O)OC)cc2)n2nnnc2N1
Answer: d. COC(=O)C1=C(C(C)=O)C(c2ccc(C(=O)OC)cc2)n2nnnc2N1
