Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -19.426\% 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=C1CC2(CCN(S(=O)(=O)c3ccccc3)CC2)Oc2ccccc21
b.) O=C(c1ccc2snnc2c1)N1CCCC1
c.) O=C(O)/C=C/c1ccc(-n2ccnc2)cc1
d.) Cc1cc(-c2cccs2)c2c(N)c(C(=O)c3ccc4c(c3)OCO4)sc2n1
Answer: a. O=C1CC2(CCN(S(=O)(=O)c3ccccc3)CC2)Oc2ccccc21
