Answer:

Option C is correct.

Explanation:

C. Buying a hammer and buying nails are dependent events. - This is correct.

Two events are said to be dependent on each other, if the occurrence of the first event affects the occurrence of the second event thus changing the probability. Here the probability for both the events is
0.10*0.40=0.04
