12 Select the option that best completes the sentence. (Hypothetical situation) They accomplish their objectives, they just need to believe in themselves. Seleccione una: a. must Ob. has to O. could

In this hypothetical situation, "must" is the best option to complete the sentence. It conveys a strong sense of necessity or obligation, suggesting that self-belief is a crucial element for achieving their goals. Without that belief, they might struggle to reach their potential. Using "has to" would imply an external requirement rather than an internal motivation, while "could" would suggest possibility rather than the imperative of believing in themselves. So, "They must believe in themselves" creates an inspiring call to action!
