Answer

Explanation:

Step1: Analyze Method 1

Salt is not magnetic, so a magnet cannot pull out salt.

Step2: Analyze Method 2

Boiling the salt - water mixture causes water to evaporate, leaving salt behind. This is a valid separation method for salt - water mixtures.

Step3: Analyze Method 3

A kitchen sieve is used to separate solid particles of different sizes. Salt in water is dissolved, so a sieve cannot separate it.

Step4: Analyze Method 4

Salt is dissolved in water and is too small to be picked out with tweezers.

Answer:

A. Method 2
