The correct answer is D. Olivia dresses neatly, rehearses what she has to say beforehand, and takes care to speak clearly.

Explanation:

In a presentation, multiple factors need to be considered this includes preparation, interaction with the audience, use of language and even dress code. A good presentation involves preparing for the presentation, interacting with the audience, speaking clearly, following a scheme, avoiding rambling or rushing, and looking formal or neatly.

In this context, Olivia is the one that is likely to make the most effective presentation because her clothes are adequate. Also, her communication and interaction with the audience are the best because by speaking clearly and rehearsing ideas she can make sure the audience understands and remembers the key information. Also, this type of communication shows she is prepared for the presentation and she knows about the topic.

ek = (m.v2) / 2

v - velocity of system after the collision

m = m1 + m2

ek = (m1 + m2) v2/2

ek = (200 + 250) 2,32/2 = 450*5,29/2 = 1190,25 j
