HF is the weakest acid halide because you need high energy to break the bond. HI can't be the weakest.

The answer is HF because in periodic trends, the strength of the hydrohalic acids increases down the group and besides, HF is a popularly known weak acid and HCl is a populary known strong acid so going with HI as the answer defies this periodic trend, indirectly saying that HF is the strongest of the hyrohalic acids which is wrong, so the correct option is C...@My School, please correct this.....

My school you have to look into this. the answer is HF because the energy required to to break the H-I bond is less than that required to break H-F bond hence HI is STRONGER than HF

The order of increasing acid strenghts= HF< HCl< HBr< HI
