Given what we know, we can confirm that the sequence on tRNA that is opposite to the codon on mRNA is the anticodon.
<h3>What is an anticodon?</h3>
This is the codon on the tRNA strand that is opposite to the mRNA codon. This opposite nature allows them to attract one another and enable their pairing in order to deposit the corresponding amino acid for protein synthesis.
Therefore, we can confirm that the sequence on tRNA that is opposite to the codon on mRNA is the anticodon.

Answer and Explanation:
The Cretaceous–Paleogene extinction, which occurred around 66 million years ago, is defined as a mass extinction that wiped out around three-quarters of species on Earth.
Among the organisms that disappeared during this event, we find mammals, birds, fish, sharks, pterosaurs, birds, reptiles, insects, and some plant species.
This event is marked by the presence of a sediment layer known as the K-Ph boundary which showed important levels of iridium, an element that is abundant in craters. Therefore, after its discovery, scientists hypothesize this extinction occurred due to the impact of the giant Chicxulub crater which changed the conditions of the atmosphere.
Testosterone is an example of an androgen.
Testosterone belongs to a class of male hormones called androgens, which are sometimes called steroids or anabolic steroids. IN men, testosterone is mainly produced in the testes. In women's bodies, testosterone is produced in the ovaries, adrenal glands, fat cells, and skin cells.
Testosterone products come in different forms, including gels, injectable solutions, patches, pills and pellets implanted under the skin. Once a patient starts testosterone therapy, the patient usually undergoes lifelong treatment. Testosterone is an anabolic steroid that occurs naturally in the human body. “Anabolic” means to build up or promote growth.
Hence, A is the correct option
