A 16 x 5 ROM storesa.5 words of 16 bits eachb.4 words of 16 bits eachc.16 words of 4 bits each

The statement seems to be incomplete. However, I can provide an explanation based on the information given.

A 16 x 5 ROM means that the ROM has 16 address lines and 5 data lines.

This means that the ROM can store 2^16 (or 65,536) different addresses. Since each address can store 5 bits of data, the total storage capacity of the ROM is 65,536 * 5 bits.

Now, let's look at the options:

a. 5 words of 16 bits each: This would require a total of 5 * 16 = 80 bits. The ROM has more storage than this.

b. 4 words of 16 bits each: This would require a total of 4 * 16 = 64 bits. The ROM has more storage than this.

c. 16 words of 4 bits each: This would require a total of 16 * 4 = 64 bits. The ROM has more storage than this.

So, based on the information given, the ROM could store any of these options, but it has the capacity to store much more.
