Correct Answer: evident

Solution : The correct choice is the second option.

The word conspicuous means easily noticeable or standing out. Among the options, evident aligns closely with this meaning. It refers to something that is clearly seen or understood, emphasising visibility or obviousness. Therefore, "evident" is an appropriate synonym for "conspicuous" in this context.

The meanings of the other options are as follows:

• Obscure : This word means unclear or not easily seen.
• Vague : This word means unclear or not clearly defined.
• Concealed : This word means hidden or not easily visible.
