it is h-i coz the Iodine molecule is huge...so the H-I bond length is big.hence, the bond is weak and easily broken. hope i am right there.

@queendrama is right
if u consider Pka values
The pKa's for the acids are as follows:

HF = 3.1
HCl = -7
HBr = -9
HI = -10

dramaqueen is right.

If the bond is the distance between two atom radii, then it would make sense that the bond of a larger atom would make a longer bond. 

Always remember:
Longer bonds = weak bond = easy to break 
Shorter bonds = strong bond = harder to break
