Widely spaced isobars indicate a :
Answer: B
Widely spaced isobars indicate a weak pressure gradient and light winds.
Isobars join places of equal pressure. When they are far apart, pressure changes little over distance, so the pressure gradient force is weak and the wind it drives is light. Closely packed isobars mean a steep gradient and strong winds, as around a cyclone.
Options A and C pair wide spacing with a steep gradient, which reverses the relationship, and option D pairs a weak gradient with strong winds, which contradicts the gradient being what drives the wind.
