the lines marked by the letters a, b, and c on the map above represent
a chains of volcanoes
b earthquake fault lines
c thin strips of heavy forests
d major rivers that flow from north to south
please select the best answer from the choices provided
a
b
c
d

Explanation:

The map (from CIA World Factbook) likely shows Southeast Asia. The lines A, B, C match the Sunda Trench - related volcanic arcs (like the Philippines, Sumatra - Java arcs). Volcanic chains are common in subduction zones here. Fault lines don't align this way, forests aren't linear strips like this, and rivers in the region (e.g., Mekong, Chao Phraya) don't flow strictly north - south in such linear chains. So the best answer is A.

Answer:

A. chains of volcanoes
