The answer is 4 π electrons.

The molecule of thiamine has two rings: pyrimidine (six-member ring) and thiazoline (five-member ring). Pyrimidine has 3 π bonds and thiazoline 2 π bonds. Since each bond contains 2 electrons, this means that the pyrimidine has 6 π electrons and thiazoline 4 π electrons.
