Let's evaluate each statement one by one to determine their truthfulness.

a. **2.3 + (-2.3) is equal to zero.**
- This statement is **true**. When you add a number and its negative, the result is always zero.

b. **(-3.7) + (-4.1) is positive.**
- This statement is **false**. Adding two negative numbers results in a more negative number. (-3.7) + (-4.1) = -7.8, which is negative.

c. (No statement given)
- This is **not applicable** since there is no content to evaluate.

d. (No statement given)
- This is **not applicable** for the same reason as above.

e. **72 - (-100) is negative.**
- This statement is **false**. Subtracting a negative number is the same as adding a positive number. 72 - (-100) is equivalent to 72 + 100 = 172, which is positive.

Based on this evaluation, the only true statement is:

- **a. 2.3 + (-2.3) is equal to zero.**
