The adrenal cortex is a vital gland that produces important hormones like cortisol, aldosterone, and androgens. Removal or dysfunction of the adrenal cortex leads to a condition known as Addison's disease, which can be fatal if untreated due to the lack of these critical hormones.
The testis produces testosterone and sperm, but its removal doesn't lead directly to death, though it can cause infertility.
The thyroid gland regulates metabolism through thyroid hormones. Although its removal leads to hypothyroidism, it is not immediately fatal as the condition can be managed with hormone replacement therapy.
The thymus gland is important for immune system development, especially in early life, but its removal does not directly result in death.
Conclusion: The removal of the adrenal cortex leads to death if not managed, which makes Option A the correct answer.

The percentage error in the measurement of mass and velocity are 3% and 4% respectively. The percentage error in the measurement of kinetic energy is:
If \( L, M, N \) are the midpoints of the sides PQ, QR, and RP of triangle \( \Delta PQR \), then \( \overline{QM} + \overline{LN} + \overline{ML} + \overline{RN} - \overline{MN} - \overline{QL} = \):
