Which of the following would define a two dimensional structure to store temperature during three periods of a day for seven days?
A) int [ , ] temp = new int [7, 3];
B) int [ , ] temp = new int [6, 2];
C) int  temp[7] [3 ] = new temp [7] [3];
D) int  temp[6] [2 ] = new temp [6] [2];

The two dimensional array should have 7 rows (for 7 days) and 3 columns (for three periods of the day). Therefore, option A is the only correct choice as it creates an array of size [7,3] which is required to store the temperatures for each period of the day for 7 days. Option B has only 6 rows and 2 columns which is insufficient for this requirement. Option C and D have incorrect syntax for creating arrays in Java.
