Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -53.586\% 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 additional words.
Options:
a.) O=C(c1cc(F)c(F)cc1Cl)N1CCN(c2ccc([N+](=O)[O-])c3ncccc23)CC1
b.) Cc1cccc2cc(/C=N/NC(=O)CN3CCOCC3)c(Cl)nc12
c.) CN(Cc1ccccc1)C1=CC(=[N+]2CCCC2)CC(C)(C)C1.[I-]
d.) Cc1cc2ccccc2n1CCNC(=O)c1ccc(Br)o1
Answer: a. O=C(c1cc(F)c(F)cc1Cl)N1CCN(c2ccc([N+](=O)[O-])c3ncccc23)CC1
