Explanation:

To determine which planet takes approximately twice as long as Earth to complete one revolution around the Sun, we use the knowledge of planetary orbital periods. Earth's orbital period (sidereal year) is about 1 year. Mars has an orbital period of approximately 1.88 years, which is roughly twice Earth's period. Venus has a shorter period (~0.62 years), Jupiter (~11.86 years), and Saturn (~29.46 years) have much longer periods. So Mars is the correct choice.

Answer:

B. Mars
