Answer:
A frameshift changes every codon past it. A base substitution only changes one codon.
Explanation:
DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.
In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:
ACTGCTATCGTCATC
If another T is added in between the first and second codons, then every codon after will be changed.
ACT>T<GCTATCGTCATC
A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:
ACTGCTATCGTCATC
Let's say the first G is replaced by a T.
ACT>T<CTATCGTCATC
As you can see, none of the other codons changed.
Typically, a frameshift mutation is considered worse than a substitution mutation.

The Correct answer is C.
The Island of Hispaniola is the second largest island in the Caribbean, at 29, 237sq miles. Haiti occupies about 1/3 of the Island while the Dominican Republic controls the balance of the land.
Christopher Columbus claimed Hispaniola in 1492, declaring it "the most beautiful island in the world". It later became the launching base for the Spanish conquest of the Caribbean, as well as the American mainland.
The western third of the island became known as Haiti in 1804 and while the remainder became known as the Dominican Republic in 1844.
