Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 11.957\% 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 COCCCn1c(SCC(=O)Nc2ccc(NC(C)=O)cc2)nc2sc3c(c2c1=O)CCC3
b CCC(=O)N(c1nnc(SCC(=O)Nc2ccccc2Cl)s1)C1CC1
c C=CCn1c(=NC(=O)C2CCCCC2)sc2cc(NC(C)=O)ccc21
d CCCCCCc1nc(C(N)=O)c2[nH]c(=O)n(-c3ccc(OC)cc3OC)c2n1
Answer: d. CCCCCCc1nc(C(N)=O)c2[nH]c(=O)n(-c3ccc(OC)cc3OC)c2n1
