Which is true for the following code?

char userText $[10]$;

userText $[0]=\text{'}B\text{'}$;

userText $[1]=\text{'}o\text{'}$;

userText $[2]=\text{'}o\text{'}$;

userText $[3]=\text{'}{k}^{\text{'}}$;

userText$[4]=\text{'}\frac{\frac{?}{?}}{0^{\text{'}}}$;

userText $[3]=\text{'}{t}^{\text{'}}$;

The compiler generates an error because element $3$ can't be overwritten.

The first four characters of the array userText are Book.

Printing the array userText will work fine because the new string is $4$ characters and the array size is $10.$

The first five characters of the array userText are Bookt.
