Problem statement: Answer the multiple choice question.
Query: Which drug has a 14.513\% 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 or b without using any other words.
Options:
a: CCOC(=O)CSc1nnc(CNc2ccc(F)cc2)o1
b: CCN1C[C@]2(COC)CC[C@H](OC)[C@@]34C1[C@]1(OCO[C@@]15C[C@H](OC)[C@H]1C[C@@H]3[C@@H]5[C@H]1OC)[C@@H](O)[C@H]24
Answer: b. CCN1C[C@]2(COC)CC[C@H](OC)[C@@]34C1[C@]1(OCO[C@@]15C[C@H](OC)[C@H]1C[C@@H]3[C@@H]5[C@H]1OC)[C@@H](O)[C@H]24
