In how many ways can the numbers $0,1,2,\dots , 9$ be arranged in such a way that the odd numbers form an increasing sequence, also the even numbers form an increasing sequence?

$ \textbf{(A)}\ 126
\qquad\textbf{(B)}\ 189
\qquad\textbf{(C)}\ 252
\qquad\textbf{(D)}\ 315
\qquad\textbf{(E)}\ \text{None}

1. We need to arrange the numbers \(0, 1, 2, \dots, 9\) such that the odd numbers form an increasing sequence and the even numbers form an increasing sequence.
2. The odd numbers in the set are \(1, 3, 5, 7, 9\), and the even numbers are \(0, 2, 4, 6, 8\).
3. Since the odd numbers must form an increasing sequence, their relative positions in the final arrangement are fixed once we choose which positions they occupy.
4. Similarly, the even numbers must form an increasing sequence, so their relative positions are also fixed once we choose which positions they occupy.
5. Therefore, the problem reduces to choosing 5 positions out of 10 for the odd numbers (or equivalently, for the even numbers).

The number of ways to choose 5 positions out of 10 is given by the binomial coefficient:
\[
\binom{10}{5}
\]

6. Calculating the binomial coefficient:
\[
\binom{10}{5} = \frac{10!}{5! \cdot 5!} = \frac{10 \times 9 \times 8 \times 7 \times 6}{5 \times 4 \times 3 \times 2 \times 1} = 252
\]

Conclusion:
\[
\boxed{252}
\]
