Problem statement: Answer the multiple choice question.
Query: Which drug has a 0.297\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a CCN(CC)c1ccc2cc(C(N)=O)c(=O)oc2c1
b O=S(=O)(c1ccc2nc(SCc3ccc(Cl)cc3)[nH]c2c1)N1CCOCC1
c O=C(CCc1c[nH]c2ccccc12)NCc1ccc2c(c1)OCO2
Answer: b. O=S(=O)(c1ccc2nc(SCc3ccc(Cl)cc3)[nH]c2c1)N1CCOCC1
