Answer:
The correct answer is (b) epinephrine.
Explanation:
Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.
In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.
When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.

Sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
<h3>What is Meiosis?</h3>
Meiosis is a particular type of cell division by which gametes (germinal cells are generated) through two division cycles known as Meiosis I and Meiosis II.
During Meiosis I homologous chromosomes are separated, thereby ensuring the correct segregation of sister chromatids during Meiosis II.
In conclusion, sister chromatids are separated during meiosis II because homologous chromosomes separate during meiosis I.
