What happens when when the stress and strain of elastic deformation along tectonic plates reaches the breaking point? select one of the options below as your
a. a volcano is created.
b. an earthquake occurs.
c. both plates are uplifted.
d. a subduction zone forms

The correct answer is b. An earthquake occurs. Basically, the earth's crust can't deal with the stress and strain so an earthquake occurs. That's why earthquakes are common where tectonic plates are unstable like the pacific area and the Western part of US. Places like Japan and San Francisco are famous for having earthquakes.

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
