The correct answer is - 3 p.m.
The Pacific Time Zone is a time zone that observes standard time by subtracting eight hours from the Coordinated Universal Time. This time zone is used in the westernmost parts of the USA, Canada and Mexico. The city of Boston is located on the total opposite side of the USA, on the eastern coast. The difference between Boston and the any place of the Pacific Time Zone is standardized to ahead hours, or better said Boston is three hours ahead since its time is counted by subtracting five hours from the Coordinated Universal Time, so it comes that when it's noon Pacific Time in Boston it is 3 p.m.
