{'planets': [6, 0, 3, 5], 'venus': [1, 0, 2, 0], 'mars': [1, 1, 1, 1], 'mercury': [0, 0, 2, 2], 'order': [6, 12, 34, 35], 'diameter': [0, 3, 3, 4], 'earth': [0, 1, 1, 1]}

The correct sequence of the given planets in increasing order of their size (diameter) is option 2: Mercury - Mars - Venus - Earth - Uranus.

Let`s dissect each option to understand why option 2 is correct.

Option 1: Mars - Venus - Earth - Mercury - Uranus

This option starts with Mars, which is smaller than both Earth and Venus. Therefore, this option is incorrect.

Option 2: Mercury - Mars - Venus - Earth - Uranus

This option follows the correct sequence. Mercury is the smallest planet, followed by Mars, Venus, Earth, and Uranus. Hence, option 2 is correct.

Option 3: Mercury - Mars - Venus - Uranus - Earth

This option starts correctly with Mercury as the smallest planet. However, it wrongly places Uranus before Earth. Therefore, this option is incorrect.

Option 4: Venus - Mercury - Mars - Earth - Uranus

This option starts with Venus, which is larger than Mercury, thus the sequence is incorrect. Therefore, option 4 is incorrect.

In conclusion, option 2 is the correct sequence of the given planets in increasing order of their size.
