If `A={x : x in N, x" is an additive inverse of "2017}` and `B={x : x in N, x" is a multiplicative inverse of "2017}`. Then `Auu B=` ________.A. `phi`B. `{-2017, 1/2017}`C. `1`D. `{2017, (-1)/2017}`

Answer» Correct Answer - A
Additive inverse of 2017 is -2017 but `-2017 notin N`
`:. A={ }`
Multiplicative inverse of 2017 is `1/2017`,
but `1/2017 notin N`
`:. B={ }`
`A uu B={ }`
Hence, the correct option is (a).
