Correct: B — walking can lengthen the walking distance. Supervised exercise therapy is first-line for claudication and improves maximal and pain-free walking distance substantially, acting through improved muscle oxygen extraction and metabolism, better endothelial function and gait efficiency rather than through the growth of new collaterals, which is modest — so option A overstates the mechanism. Exercise also improves coronary risk and the control of risk factors, so options C and D are wrong.
