hello your question lacks the required option, below are the missing options

A. The transaction data in the tampered block is deleted, and a copy is created with the same hash value.

B. The hash values of transaction data of subsequent blocks are validated, and the chain is broken.

C. The hash value for the entire block is nullified, creating a domino effect on all subsequent blocks.

D. The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues.

answer : The hash values of subsequent blocks are updated as soon as they are tampered with, and the chain continues ( D )

Explanation:

What happens if a transaction data is changed in an earlier existing block in a Blockchain is that the Hash values of subsequent blocks will be updated as soon as they are tampered with and the chain will continue.

Blockchain is a specially design system for recording information, hence any change in data inputted in an earlier existing blocks that changes will automatically be updated as well in all preceding blocks.

For question 1, i'm a bit stuck between serif fonts or large enough type to read. serif fonts are good fonts to use because their easy to read. but you also need your type be large enough to read. if i had to say what you need to consider most important, i would say d is the answer. for question 3, i believe the answer is d. it seems most appropriate to do that. on every page or every other page would be too much, and only on the contact page just seems inappropriate. for question 4, it's probably a. by "color scheme" it doesn't mean just one color, but a set of colors. colors that are complimentary to each other. having too many is too distracting so it's best to limit it as much as possible, but not to the point where your website looks dull.hope this !
