How should you correctly invoke vTaskList() to store the task status information in a character array named taskInfo?

AvTaskList(taskInfo);

BvTaskList(&taskInfo);

CvTaskList();

DvTaskList(&taskInfo[0], sizeof(taskInfo));

Step-by-Step Solution

Solution:

Step 1: Check function prototype
vTaskList() takes a single parameter: a pointer to a character buffer.
Step 2: Passing the buffer
Passing taskInfo (an array) decays to a pointer to its first element, which is correct.
Step 3: Incorrect options
Passing &taskInfo is a pointer to the array, not a char pointer. Calling without parameters is invalid. Passing size is not supported by vTaskList().
Final Answer:
vTaskList(taskInfo); -> Option A
Quick Check:
Remember, arrays decay to pointers when passed to functions [OK]

Quick Trick: Pass buffer name directly to vTaskList() [OK]
