Assume receiving "Embedded System" using UART code. Determine the number of missing instruction(s): void main ( ) {char y[15]; UART1_init(9600); while(1) { if (UART1_DATA_READY ( ) == 1) {y[i] = UART1_READ (); i++;} } } Select one: A. Two instructions B. One instruction C. No missing instructions D. More than two
