Explanation:

Given Information:
- A teaches Mathematics which is not taught in the first period.
- Physics is taught by D in an even numbered period.
- Chemistry is taught in an odd period, and it precedes Mathematics period.
- E teaches in the first period.
- C teaches Chemistry but not in the first or the last periods.
- Hindi is taught in the last period.

Analysis:
- From the given information, we can deduce the following:
- Mathematics cannot be taught in the first period, so it must be taught in either the second, third, fourth, or fifth period.
- Physics is taught by D in an even-numbered period, so it must be in the second or fourth period.
- Chemistry is taught in an odd period and precedes the Mathematics period, so it must be in the first or third period.
- E teaches in the first period, so Physics cannot be taught in the first period.
- C teaches Chemistry but not in the first or last periods, so Chemistry must be taught in either the second, third, or fourth period.
- Hindi is taught in the last period.

Solution:
- Based on the above analysis, we can determine that the fourth period is of Mathematics taught by A because Mathematics cannot be taught in the first period and must be in the second, third, fourth, or fifth period. Therefore, the statement "Fourth period is of Mathematics taught by A" is necessarily true.
