Answer:
B). To make progress, you have to accept the risks that come with it.
Step-by-step explanation:
Theme is demonstrated as the elemental message, idea, or teaching that the author wishes to convey to the audience through his work. It is usually universal in approach and functions to unify the text together in a coherent thought.
As per the question, the second option exemplifies a theme as it reflects a universal message that Marie Curie's story is conveying to the students that 'in order to make progress and success in life, one is required to display acceptance towards the risks and barriers coming in the way.' It unifies the text in a single coherent idea/thought. Thus, option B is the correct answer.
