Problem statement: Answer the multiple choice question.
Question: Which drug has a 4.022\% 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(/C=C/c1ccccc1)Nc1nc(-c2ccncc2)cs1
b) O=[N+]([O-])c1cc(S(=O)(=O)/N=C(/c2ccccc2)N2CCOCC2)ccc1Cl
c) CCCNC(=O)c1ccc(N2CC3CC(C2)c2cccc(=O)n2C3)c(NC(=O)Nc2ccc(CC)cc2)c1
d) Cc1cccc(OP(=O)(Nc2c(C)n(C)n(-c3ccccc3)c2=O)Oc2cccc(C)c2)c1
Answer: a. O=C(/C=C/c1ccccc1)Nc1nc(-c2ccncc2)cs1
