Hint:

To remember meteorological isolines:
- Isohel $\rightarrow$ Helios (Sun) $\rightarrow$ Sunshine Duration
- Isoneph $\rightarrow$ Nephos (Cloud) $\rightarrow$ Cloud Cover
- Isotach $\rightarrow$ Tach (Speed) $\rightarrow$ Wind Velocity
- Isotherm $\rightarrow$ Therme (Heat) $\rightarrow$ Temperature

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
In agricultural meteorology and geography, isopleths are isolines drawn on maps to connect locations that share equal values of a given meteorological or physical parameter.

Step 3: Detailed Explanation:
Let us match the meteorological terms with their definitions:
- (A) Isohels: These are lines connecting points on a map that receive equal durations of sunshine. It matches with (II) Sunshine Duration (derived from the Greek root *helios*, meaning sun).
- (B) Isonephs: These are lines connecting points on a map with equal average cloud cover. It matches with (IV) Cloud Cover (derived from the Greek root *nephos*, meaning cloud).
- (C) Isotachs: These are lines connecting points on a map with equal wind speed or velocity. It matches with (I) Wind Velocity (derived from the Greek root *tachys*, meaning swift or speed).
- (D) Isotherms: These are lines connecting points on a map that share the same temperature. It matches with (III) Temperature (derived from the Greek root *therme*, meaning heat).
This matching sequence yields: (A)-(II), (B)-(IV), (C)-(I), (D)-(III), which corresponds to Option (B).

Step 4: Final Answer:
The correct matching sequence is (A)-(II), (B)-(IV), (C)-(I), (D)-(III).
