Concept:Children of the same age, regardless of gender, have equal cognitive abilities, reasoning skills, and problem-solving capacities.
Explanation:Research shows that boys and girls possess similar brain development and learning potential at the same age.
Option A is incorrect because girls do not inherently face difficulty in reasoning; they can reason as well as boys.
Option C is also wrong — girls perform equally well in mathematical concepts compared to boys of their age.
Option D is eliminated because there is no evidence that girls always have more linguistic or musical abilities; these skills vary individually.
Therefore, the correct conclusion is that girl students are as good in Mathematics as boys of their age.
Answer:B. are as good in Mathematics as boys of their age
