To determine how Washington gained control of Boston, we need to review the options and eliminate the incorrect ones.

1. He sent 16,000 troops to launch a surprise attack on the British fort protecting Boston.
While it is true that Washington's army surrounded Boston, he did not send a force of 16,000 troops to launch a surprise attack on a fort. This option is incorrect.

2. He gained the trust of Native Americans who led a deadly attack on the British.
There is no historical evidence to suggest that Washington gained control of Boston by gaining the trust of Native Americans who led a deadly attack on the British. This option is incorrect.

3. He surrounded the harbor, giving them no option other than to surrender.
This option is correct. Washington and his army strategically surrounded the harbor, cutting off British supply lines and isolating the city. This surrounded the British forces, leaving them with no option other than to surrender.

4. He strategically placed cannons overlooking the harbor which forced out the British.
While Washington did strategically place cannons overlooking the harbor to put pressure on the British, this action alone did not lead to gaining control of Boston. This option is partially correct, but it does not provide a complete explanation.

Therefore, the correct answer is:
3. He surrounded the harbor, giving them no option other than to surrender.

By surrounding the harbor and cutting off the British supply lines, Washington forced the British into a vulnerable position. Without the ability to receive reinforcements or supplies, the British were left with no choice but to surrender, thus giving Washington control of Boston.
