Answer:
Option A
Explanation:
Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is
a) over- or underproduction of thyroid hormones
b) Nodules in the glans
Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing the thyroid to swell
Thus, Option A is correct
Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.

From what i understand of the question, its water? Im not sure exactly what the question is asking, sorry :/
Answer:
Please find the explanation below.
Explanation:
Changes in the genetic sequence of a DNA is called MUTATION. A gene is a segment of the DNA that holds information for the synthesis of proteins, which are responsible for the observable traits in organisms. The expression of a gene brings about the synthesis of a protein that effects a particular trait in an organism. The gene is expressed in two major stages viz: transcription and translation.
Transcription involves production of an mRNA molecule using the encoded information in the genes of a DNA while translation is the synthesis of a protein using the mRNA as a template.
Since, the order of the sequence in a gene determines the order of the sequence in the mRNA which ultimately determines the order of sequence in the protein, a change in the gene of an organism will affect the observed trait of that organism.
More detailedly, a change in the gene will cause a change in the mRNA sequence during transcription. A change in the mRNA sequence will cause a change in the amino acid sequence during translation. A change in the amino acid sequence will affect the protein produced i.e. might not be functional or may not be produced at all. An affected protein will cause a trait in that organism to be affected.
