1.Let S1,S2S_1, S_2S1,S2 and S3S_3S3 be three sets defined as S1={z∈C:∣z−1∣≤2}S_1 = \{z \in \mathbb{C} : |z - 1| \le \sqrt{2}\}S1={z∈C:∣z−1∣≤2}, S2={z∈C:Re((1−i)z)≥1}S_2 = \{z \in \mathbb{C} : \mathrm{Re}((1 - i)z) \ge 1\}S2={z∈C:Re((1−i)z)≥1} and S3={z∈C:Im(z)≤1}S_3 = \{z \in \mathbb{C} : \mathrm{Im}(z) \le 1\}S3={z∈C:Im(z)≤1}. Then, the set S1∩S2∩S3S_1 \cap S_2 \cap S_3S1∩S2∩S3a.is a singleton.b.has exactly two elements.c.has infinitely many elements.d.has exactly three elements.Login to continueOnly logged in users canattempt or see the solution.
