Answer:
b) A series of stars that form a figure
Explanation:
In astronomy, <em>a constellation is any of certain groupings of stars that form an imaginary outline or pattern on the celestial sphere. </em>They are useful to track artificial satellites and in assisting astronomers and navigators to locate certain stars, therefore constellation is a series of stars that form a figure. A constellation can't be a region of the celestial sphere and all of the stars in it because not all stars in the celestial sphere form figures.
They are no figures in the night sky because constellations are starts, therefore they are present during day or night, it's not a term applicable to astrology because this is a pseudoscience not based on facts, like astronomy.

Currents involve movement of ocean water masses, driven either by wind or by differences in temperature, salinity and density. The most important from a human perspective are the wind-driven surface currents that move water in the uppermost layer of the ocean.
Currents affect humans in several primary ways. Currents help shape the climate in the areas where we live, create the right conditions to support abundant ocean life in the areas where we fish, and change weather patterns through periodic events like El Nino/La Nina.
Ocean currents also cause upwelling in many areas like off in the inland parts of North America, where surface currents taking water away from the shore cause nutrient-rich water to well up from the ocean deeps. The abundance of nutrients in these areas forms fertile ground for kelp beds and marine fisheries, which in turn furnish food for humans. Alterations in current patterns like the El Nino/La Nina cycle affect humans as well by causing changes in local weather patterns in the years when they occur.
