Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.391\% 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.) O=C(Nc1cc(Cl)ccc1-n1cncn1)c1ccc([N+](=O)[O-])s1
b.) COC(=O)COc1ccc(-n2cnnn2)cc1
c.) Cc1ccc(N/C(N)=N/c2nc(CSc3nnc(N)s3)cc(=O)[nH]2)cc1
d.) COc1ccccc1/C=C/C=C1\Oc2c(ccc(O)c2CN2CCN(CCO)CC2)C1=O
Answer: a. O=C(Nc1cc(Cl)ccc1-n1cncn1)c1ccc([N+](=O)[O-])s1
