E.	None of these

Answer and Explanation

Answer:C

Explanation:
0.7 is double constant (Default). Its binary value is written in 64 bit. Binary value of 0.7 = (0.1011 0011 0011 0011 0011 0011 0011 0011 0011 0011 0011) Now here variable a is a floating point variable while 0.7 is double constant. So variable a will contain only 32 bit value i.e. a = 0.1011 0011 0011 0011 0011 0011 0011 0011 while 0.7 = 0.1011 0011 0011 0011 0011 0011 0011 0011 0011 0011 0011.... It is obvious a < 0.7
