Correct choice is (b) opening the blockages in blood vessels

To explain: Angioplasty, also known as balloon angioplasty is a process by which the blockages in the blood vessels are opened. Blockages are due to the deposition of plaque and they reduce the blood flow. Thus, the vessels narrow out and cause blockages which need to be removed. For this process, a catheter is inserted followed by a balloon catheter. Once the balloon is in place, it is inflated and the plaque and the capillary walls are pushed aside, opening the blockage.
