Identify the option that demonstrates the most appropriate usage of an adjective clause.

She took a six-week course.

The correct answer is Option (4) → She took a six-week course.

• Understanding the question:

  • An adjective clause is a dependent clause that modifies a noun or pronoun and provides additional information about it.

• Analyzing the options:

  • Option 1: "She is senior and most intelligent than her friend."

    • Incorrect because "senior" and "most intelligent" are adjectives, but there is no adjective clause present.
    • The phrase is also grammatically incorrect as "more intelligent" is the correct form, not "most intelligent than."

  • Option 2: "Meera adopted a Two-years-old girl."

    • Incorrect because it is grammatically flawed. "Two-years-old" should be "two-year-old" to modify "girl."

  • Option 3: "This tree is to big as the other tree."

    • Incorrect because "to big" is a typographical error; it should be "too big."
    • This sentence does not contain an adjective clause.

  • Option 4: "She took a six-week course."

    • Correct because the phrase "six-week" is an appropriate adjective modifying the noun "course."
