Verified by Experts

The correct Answer is:
A
The bond strength H-X decreases from HF to HI. Thus HF is the most stable and hence weakest acid while is least stable and most acidic. In aqueous solutions. HF is only slightly ionised. As basicity is the reverse of acidity . Therefore HF is the most basic of all H-X
