B{'text': 'Gigantism with great height'}
C{'text': 'Goitre in the neck region'}
D{'text': 'Diabetes with high sugar'}
Answer & Solution
Correct answer: B. {'text': 'Gigantism with great height'}
1. Growth hormone controls height growth during childhood.
2. **Too little** growth hormone → dwarfism; **too much** growth hormone before adulthood → **gigantism**.
3. Goitre is a thyroid disorder; diabetes is from insulin deficiency.
4. Hence excess growth hormone in childhood causes gigantism.
