Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.191\% 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(NCc1ccco1)C1CCCN(S(=O)(=O)c2ccc(Br)cc2)C1
b O=C(CCNC(=O)c1ccc(Br)cc1)NCC1COc2ccccc2O1
c O=C(NCCN1CCOCC1)c1ccc2ccccc2n1
d Cc1nc([N+](=O)[O-])c(SCC(O)CCl)n1Cc1ccc(Cl)cc1
Answer: b. O=C(CCNC(=O)c1ccc(Br)cc1)NCC1COc2ccccc2O1
