General KnowledgeGeography
- ABoth the statements are individually true and Statement II is the correct explanation of Statement I
- BBoth the statements are individually true but Statement II is not the correct explanation of Statement I
- CStatement I is true but Statement II is false
- DStatement I is false but Statement II is true
Explanation
Incised (entrenched) meanders form when a meandering river is rejuvenated by uplift or a fall in base level: the river cuts vertically downward, preserving its curves in a gorge. They are therefore not products of the mature stage, which features free meanders on a floodplain, so Statement I is false. Statement II correctly attributes them to rejuvenation and upliftment, so it is true. Hence Statement I is false but Statement II is true.
