Cardiac cycle refers to the complete sequence of events that occur during one heartbeat, including the contraction and relaxation of the heart muscle. The duration of a cardiac cycle is given as 0.8 seconds. To calculate the number of cardiac cycles that occur in 4 minutes, we need to convert the given time into seconds and divide it by the duration of one cardiac cycle.

1. Convert 4 minutes into seconds:
- 1 minute = 60 seconds
- 4 minutes = 4 x 60 = 240 seconds

2. Calculate the number of cardiac cycles:
- Number of cardiac cycles = Total time / Duration of one cardiac cycle
- Number of cardiac cycles = 240 seconds / 0.8 seconds
- Number of cardiac cycles = 300

Therefore, the correct answer is option 'D' which states that 300 cardiac cycles occur in 4 minutes.

In summary:
1. Conversion: 4 minutes = 240 seconds
2. Calculation: Number of cardiac cycles = 240 seconds / 0.8 seconds = 300
