Answer: A. 4.3\times10^7

Step-by-step explanation:

Given : A certain CD-ROM disk can store approximately 6.0 \times 10^2  megabytes of information.

1 megabyte = 10^6 bytes

Then, The storage capacity of CD-ROM disk will be :

10^6\times 6.0 \times 10^2=6\times10^{6+2}=6\times10^8  

If an average word requires 14 bytes of storage, then the number of words can be stored :-

\dfrac{6\times10^8}{14}=0.428571428571\times10^8\approx0.43\times10^8=4.3\times10^7

Hence,  number of words can be stored = 4.3\times10^7
