1.Let A={z∈C:1<∣z−(1+i)∣<2}A = \{z \in \mathbb{C} : 1 < |z - (1 + i)| < 2\}A={z∈C:1<∣z−(1+i)∣<2} and B={z∈A:∣z−(1−i)∣=1}B = \{z \in A : |z - (1 - i)| = 1\}B={z∈A:∣z−(1−i)∣=1}. Then, BBB:a.is an empty set.b.contains exactly two elements.c.contains exactly three elements.d.is an infinite set.Login to continueOnly logged in users canattempt or see the solution.
