Answer:
The correct answer is C. The main difference between Sikhism and Hinduism is that Sikhism teaches that there is only one God.
Step-by-step explanation:
Sikhism accepts the Hindu belief in karma and reincarnation, but preaches a simple way to end the cycle by leading a disciplined life. The Sikhs believe that through the grace of God and with constant meditation and repetition of His name, one can be liberated from the cycle of birth and death. Guru Nanak explained to his followers that the birth is due to karma, but the release is due to the grace of God. Guru Nanak taught that salvation does not mean entering Paradise after a final judgment, but that it is union and absorption within God.
Sikhism is, in essence, a monotheistic religion, and for that reason it has more in common with Islam than with Hinduism or Buddhism.
