Task: Answer the multiple choice question.
Question: Which drug exhibits a -7.335\% 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 COc1ccc(CNC(=O)CN(Cc2ccc(OC)cc2)C(=O)c2csnn2)cc1
b COc1cc(OC)c(N(C)C(=O)c2cn(C)c(=O)c3cc(OC)c(OC)cc23)cc1Cl
c O=C(O)c1ccc(C[n+]2c(-c3ccccc3)csc2Nc2ccccc2)cc1.[Br-]
d CCn1c(C)nc2cc(NC(=O)Nc3cccc(C(C)=O)c3)ccc21
Answer: a. COc1ccc(CNC(=O)CN(Cc2ccc(OC)cc2)C(=O)c2csnn2)cc1
