Reason (R): Mid oceanic ridge runs through the centre of five oceans.

पर्याय

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

A is false and R is true.

Explanation:

The mid oceanic ridge is volcanically active; it is the site of most underwater volcanic eruptions, as it is a divergent boundary where tectonic plates pull apart. However, the reason given (that the ridge runs through the center of five oceans) is true but not a reason for volcanic inactivity.
