Correct answer: C
Concept
Soil names and properties are distinct kinds of facts. A soil type may be identified by a regional name, while its mineral profile is established from its characteristic constituents; each statement must therefore be tested independently.
Application
Apply the two checks separately:
The name check: black soil is also called Regur, so the first statement records its accepted regional name.
The composition check: black soil is characteristically rich in calcium carbonate or lime, calcium, potash and iron-bearing minerals, so the second statement records recognized constituents of this soil.
Contrast
Contrast the offered combinations by value:
Only 1 accepts the name fact but excludes the mineral-composition fact.
Only 2 accepts the mineral-composition fact but excludes the name fact.
The combination “Both 1 and 2” accepts the name fact and the mineral-composition fact together.
The combination “Neither 1 nor 2” rejects both the name fact and the mineral-composition fact.
Result
Both independent checks hold; therefore, the result is Both 1 and 2.
