Hence,

Correct Answer: SUW

Solution : Given:
ACE : GIK :: MOQ : ?

Add 6 to the place value of each letter of ACE to obtain the required code –
A + 6 = G; C + 6 = I; E + 6 = K

The meanings of

Correct Answer: 6.5 cm

Solution : Given, Base = 1.6 cm and Perpendicular = 6.3 cm
Applying Pythagoras theorem, we get,
$\small\text{Hypotenuse}^2 = \text{Base}^2+\text{Perpendicular}^2$
⇒ $h^2=(1.6)^2+(6.3)^2$
⇒ $h^2=2.56+39.69=42.25$
⇒ $h=\sqrt{42.25}=6.5$ cm
Hence, the correct answer is 6.5 cm.

Correct Answer: Certainty

Solution : The correct choice is the second option.

The most appropriate antonym for potential is certainty because potential implies possibility or capability while certainty means absolute assurance or confidence in the inevitability of something happening or the absence of doubt.
