1.A boat moves relative to water with a velocity which is nnn times the river flow velocity.Note: More than one option may be correct.a.If n<1n < 1n<1, boat cannot cross the riverb.If n=1n = 1n=1, boat cannot cross the river without driftingc.If n>1n > 1n>1, boat can cross the river along shortest pathd.Boat can cross the river whatever is the value of nnn (excluding zero)Login to continueOnly logged in users canattempt or see the solution.
