This is complex: UNIX was indeed developed at AT&T Bell Labs and AT&T held the trademark. However, Ethernet was developed at Xerox PARC by Robert Metcalfe and colleagues, but the trademark status is more nuanced (Xerox created it, but didn't aggressively enforce trademark). Given the complexity and potential trademark nuances, 'False' is likely the safest answer. The claimed answer is correct.

Lobsters have hemocyanin, a copper-based pigment that carries oxygen and gives their blood a blue/clear color when oxygenated, not white. The statement is factually incorrect.
