Answer:
The option B. q = 43.0 is correct
Step-by-step explanation:
Whole Number : It is defined as non-negative integer whose fraction or decimal part is always 0.
Now, it is given that q is a whole number between 42.3 and 43.1
So, to find q :
The given options are :
A. q = 42.1 : As the decimal part is not 0 in 42.1 so it cannot be whole number. So this option is rejected.
C. q = 43.4 : As the decimal part is not 0 in 43.4 so it cannot be whole number. So this option is rejected.
B. q = 43.0 : The decimal part in 43.0 is 0 so it is an whole number.
Also 42.3 < q = 43.0 < 43.1
So, the required value of q = 43.0
Hence, The option B. q = 43.0 is correct
