+ AnswerC

+ ExplanationReturn type of printf function is int. This function return a integral value which is equal to number of charcters printf function will print on console.

Operator >= will return 1 if both operands are either equal or first operand is grater than second operand. So a>=10 will return 1 since a is equal to 10.Thus printf function will print 1. Since this function is printing only one character so it will also return 1.    So, printf("%d",a>=10) - 10
= 1 - 10
= -9

Since -9 is non-zero number so if(-9) is true condition hence if clause will execute which contains an infinite loop but due to break keyword it will come out of loop.
