- Salinity is a measure of the amount of salt dissolved in seawater.

- It is usually expressed in parts per thousand (ppt or ‰).

- Option 1: 100 gm

- Incorrect: Salinity is not typically gauged against just 100 gm of seawater.

- Option 2: 10 gm

- Incorrect: This would make the calculation too sensitive to minor variations.

- Option 3: 1000 gm

- Correct: Standard salinity measurement is grams of salt per 1000 gm (or 1 kg) of seawater.

- Option 4: 10,000 gm

- Incorrect: This scale is larger than necessary for practical measurements.
