Given that string[] str has been initialized, to get a copy of str[0] with all characters converted to upper case, use the following statement:
a. str[0].touppercase();
b. str. touppercase();
c. str[0].uppercase();
d. str. uppercase();

str[0].toUpperCase();

Explanation:

str[0] is pointing to the first character of the entire string and the code str[0].toUpperCase() will convert the characters to upper case if they are in lowercase and will remain unchanged if they are already in upper case.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
