Question

Choose the CORRECT match between items in Group I with the items in Group II. 
Group I                      Group II 
P. Polarity zone           1. Biostratigraphy 
Q. Formation               2. Chronostratigraphy 
R. Biozone                   3. Magnetostratigraphy 
S. Epoch                      4. Lithostratigraphy 
 

• A. P–1; Q–2; R–3; S–4
• B. P–2; Q–3; R–1; S–4
• C. P–3; Q–4; R–1; S–2
• D. P–3; Q–4; R–2; S–1

Hint:

Remember the association: Magneto → Polarity, Litho → Rock unit, Bio → Fossils, Chrono → Time.

Answer 1

The Correct Option is C

Step 1: Understanding stratigraphic divisions.
- Polarity zone: Based on magnetic field reversals → Magnetostratigraphy.
- Formation: Fundamental unit of rock layers → Lithostratigraphy.
- Biozone: Defined by fossil content → Biostratigraphy.
- Epoch: Subdivision of geologic time → Chronostratigraphy.
Step 2: Matching.
P–3 (Polarity zone → Magnetostratigraphy), Q–4 (Formation → Lithostratigraphy), R–1 (Biozone → Biostratigraphy), S–2 (Epoch → Chronostratigraphy).
Step 3: Conclusion.
The correct match is (C) P–3; Q–4; R–1; S–2.
