Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.041\% 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(COc1ccccc1)NCC(c1ccco1)N1CCN(c2ccccc2)CC1
b. CSCCC(=O)N1CCCC(N2CCN(c3cccc(C(F)(F)F)c3)CC2)C1
c. O=S(=O)(NCC(c1ccco1)N1CCOCC1)c1ccc(Cl)cc1
d. Cc1cc2c(ncn2C(C)C)c(NS(=O)(=O)c2ccc(F)cc2)c1C
Answer: a. O=C(COc1ccccc1)NCC(c1ccco1)N1CCN(c2ccccc2)CC1
