Best answer
Right option is (c) Small

To explain I would say: Commercial DTA instruments are available which enable the temperature range-190 to 1600 degree Celsius to be covered. Sample sizes are usually small, a few milligrams because then there is less trouble with thermal gradients within the sample which could lead to reduced sensitivity and accuracy.
