Que. | Let L be any language. Define even (W) as the strings obtained by extracting from W the letters in the even-numbered positions and even (L) = {even (W) | W ԑ L}. We define another language Chop (L) by removing the two leftmost symbols of every string in L given by Chop(L) = {W | v W ԑ L,with | v | = 2}.
If L is regular language then |

a. | even (L) is regular and Chop(L) is not regular |

b. | Both even(L) and Chop(L) are regular |

c. | even(L) is not regular and Chop(L) is regular |

d. | Both even (L) and Chop(L) are not regular |

Answer:Both even(L) and Chop(L) are regular |
