Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -2.562\% 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=C1CN(C(=O)c2ccccc2F)C(c2ccccc2)c2cc(F)ccc2N1
b Cl.c1ccc(-n2cnc3cc(NCc4ccccn4)ccc32)cc1
c NC(=O)c1c(/N=C/c2cccnc2)sc2c1CCCC2
d O=c1[nH]c(O)c(/C=C2\C=NN=C2c2ccccc2)c(=O)[nH]1
Answer: a. O=C1CN(C(=O)c2ccccc2F)C(c2ccccc2)c2cc(F)ccc2N1
