Answer:
C. empirical evidence
Explanation:
Empirical evidence is a type of knowledge obtained through sensory experience, that is, through the process of observation and experimentation. Empirical evidence is often used during the application of the scientific method to test a hypothesis. In the example in question, Peter Grant obtained empirical evidence about birds' biology to verify that his assumptions about their evolution were correct.
There are choices for this question namely:
<span>a. Human immunodeficiency virus (HIV)
b. T-lymphocyte virus type I
c. Epstein-Barr virus
d. Parvovirus
e. Poxvirus

The correct answers are HIV, T-lymphocyte virus type I, and Epstein-Barr virus. HIV or human immunodefiency virus will predispose the patient in developing Kaposi sarcoma in later stages of acquired immunodeficiency syndrome. T-lymphocyte virus type I is believed to be the etiological agent for developing T-cell leukemia or lymphoma. Epstein-Barr virus is associated with both nasopharyngeal carcinoma and Burkitt lymphoma.
<em>Parvovirus B19 causes a viral exanthem called erythema infectiosum which has no propensity to malignancy. Poxvirus is the etiologic agent for molluscum contagiosum, also with no propensity in developing malignancy. </em>
They consist of identical sister chromatids
