**Language Definition and Regular Expression Problem****Problem Definition:**Let \( A \) be the language defined as follows:\[ A = \{ x \in \{0,1\}^* \mid \text{the number of 0s in } x \text{ is } 4k+1 \text{ or } 4k+2 \text{ for some integer } k \} \]**Question:**Which of the following regular expressions represents the language \( A \)?**Options:**1. \((1^*01^*01^*01^*01^*) \cup (1^*01^*01^*01^*01^*01^*)\)2. \((1^*0) \cup (1^*01^*0)(1^*00001^*)^*\)3. \(1^*01^*01^*01^*((01^*) \cup (01^*01))\)4. \((1^*01^*01^*01^*01^*) \cup (1^*01^*01^*01^*01^*01^*01^*)\)5. \(0^*1^*01^*01^*01^*01^*0\)**Explanation of the Problem:**The question asks us to identify which regular expression matches the language \( A \), where the sequence consists of binary strings with the number of 0s being either \( 4k+1 \) or \( 4k+2 \) for some integer \( k \). **Explanation of Choices:**1. **Option 1:** Repeated sequence of blocks with four and five "01" patterns, corresponding to possible counts of '0' being \( 4k+1 \) or \( 4k+2 \).2. **Option 2:** Initial option combined with an additional zero, suggesting a form of counting of zeros.3. **Option 3:** Variably builds the expression with sequences that logically group patterns of one or two repetitions of certain sequences.4. **Option 4:** Larger repetition and combination of sequences indicating separate instances that might fit the criteria.5. **Option 5:** Suggests a possible singular sequence but likely does not cover the full breadth of possibilities.Understanding these options requires familiarity with the rules of
