Task: Answer the multiple-choice question.
Question: Which drug has a 6.557\% human ether-à-go-go related gene (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(Nc1nc(-c2ccc(S(=O)(=O)N3CCCCCC3)cc2)cs1)c1cccs1
b. CCC(=O)NC(=S)Nc1ccc(NC(=O)c2ccc(Br)o2)cc1
c. O=C(Nc1ccccc1)c1c(O)[nH]c(=O)[nH]c1=O
d. O=C(c1ccc2oc(Cc3ccc(Cl)cc3)nc2c1)N1CCCCC1CCO
Answer: d. O=C(c1ccc2oc(Cc3ccc(Cl)cc3)nc2c1)N1CCCCC1CCO
