3. 2001年5月5日,甲拒绝向乙支付到期租金,乙忙于事务一直未向甲主张权利。
2001年8月,乙因出差遇险无法行使请求权的时间为20天。
根据《民法通则》的有关规定,乙请求人民法院保护其权利的诉讼时效期间是。
A.自2001年5月5日至2002年5月5日D.自2001年5月5日至2003年5月25日答案:A[解答] ①拒付租金的,适用于1年的特别诉讼时效期间(2001年5月5日至2002年5月5日);②只有在诉讼时效期间的“最后6个月内”(2001年11月5日至2002年5月5日)发生不可抗力和其他障碍(出差遇险),才能中止诉讼时效的进行。
如果在诉讼时效期间的最后6个月前发生不可抗力,至最后6个月时不可抗力已消失,则不能中止诉讼时效的进行。
