Match List I with List II:

	LIST I (Reagents used)		LIST II (Compound with Functional group detected)
A.	Alkaline solution of copper sulphate and sodium citrate	I.
B.	Neutral $$\mathrm{FeCl_3}$$	II.
C.	Alkaline chloroform solution	III.
D.	Potassium iodide and sodium hypochlorite	IV.

Choose the correct answer from the options given below:

The number of given statement/s which is/are correct is __________.

(A) The stronger the temperature dependence of the rate constant, the higher is the activation energy.

(B) If a reaction has zero activation energy, its rate is independent of temperature.

(C) The stronger the temperature dependence of the rate constant, the smaller is the activation energy.

(D) If there is no correlation between the temperature and the rate constant then it means that the reaction has negative activation energy.
