Option c

Explanation:

Nancy Bayley developed Bayle scale which is a series of tests that assess the development of toddlers and infant between the ages of 1 - 42 months. The tests are conducted by exposing a child to play tasks which last for 45-60 minutes. Furthermore, the child’s score is compared to the normal child’s development responses. It also checks development quotient instead of intelligent quotient.  

When analyzing the intelligence of child geniuses, it was found that most adults who were in their late 30's to early 40's were still improving in their learning capabilities. That is their vocabulary, comprehension and information were still improving.
