Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.990\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(N/N=C/c1ccc(O)c2ccccc12)c1cccnc1
b.) C=CCC1(CC=C)CCCN1C(=O)CC1C(=O)NCCN1Cc1cccc(OC)c1
c.) Cc1ccc2sc(N3CCN(CCNC(=O)c4ccco4)CC3)nc2c1C.Cl
Answer: a. O=C(N/N=C/c1ccc(O)c2ccccc12)c1cccnc1
