Question

Match List - I with List - II.

Choose the correct answer from the options given below :

• A. A-I, B-II, C-IV, D-III
• B. A-III, B-II, C-I, D-IV
• C. A-III, B-IV, C-I, D-II
• D. A-IV, B-III, C-II, D-I

Hint:

Mensuration Definitions:
- Quarter Girth Formula $\rightarrow$ Volume estimation ($V$).
- DBH $\rightarrow$ Stem Diameter ($D$).
- Girth ($G$) $\rightarrow$ $\pi \times D$.
- Hypsometer $\rightarrow$ Instrument to measure Tree Height.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks to match forest mensuration parameters/formulas in List - I with their defining mathematical relationships or measuring instruments in List - II.

Step 2: Detailed Technical Matching:

• A. Quarter Girth Formula: Hoppus' quarter girth rule calculates timber log Volume ($V = \left(\frac{G}{4}\right)^2 \times L$) $\rightarrow$ III.
• B. Breast Height: Standard reference height ($1.37\text{ m}$) at which tree Diameter (DBH) is recorded $\rightarrow$ IV.
• C. Girth ($G$): The perimeter of a circular stem given by $G = \mathbf{\pi D}$ $\rightarrow$ I.
• D. Tree Height: Measured using hypsometric instruments (e.g., Haga Altimeter, Blume-Leiss Hypsometer) $\rightarrow$ II.

Step 3: Verification of Combition:

• A $\rightarrow$ III
• B $\rightarrow$ IV
• C $\rightarrow$ I
• D $\rightarrow$ II
• This corresponds to option (C): A-III, B-IV, C-I, D-II.

Step 4: Fil Answer:
The correct matched sequence is A-III, B-IV, C-I, D-II, corresponding to option (C).
