If light travels 300,000 per second it will travel 300,000*60= 18,000,000 per minute
so 1 light minute = 18,000,000 km 
 Now if 18,000,000 is 1 light minute then 150,000,000 will be 150,000,000/18,000,000=8.3 =8 1/3 so the c option is correct

V(sec)=3*100000 km/s
v(min)=18*1000000 km/s
DIstance=150000000
time taken =150000000/18000000=25/3=option (c)
