The right answer is "2.) hinduism was the first monotheistic religion in India and is still widely practiced across the nation ".
There is some confusion about the concept of God in Hinduism, but the explanation for this alternative being the correct answer to your question is that Hinduism is a diversified system of thinking, with beliefs encompassing monotheism, polytheism, panentheism, pantheism, monism, and atheism, and his concept of God is complex, and is tied to each of his traditions and philosophies. It is sometimes regarded as a henotheistic religion (that is, it involves devotion to a single god, although it accepts the existence of others), but the term is seen, like the others, as an over-generalization.
