参考解析：

结合题干和选项，可以定位至文章第二段。A项：In July, Sundar Pichai, CEO of Google parent Alphabet Inc. , pledged $10 billion to digitize India, including a $4.5 billion investment in Jio. 谷歌母公司Alphabet的首席执行长皮查伊承诺斥资100亿美元实现印度的数字化；B项：This year's investment rush began in January when Amazon.com Inc. founder Jeff Bezos, declared “the 21st century will be India's”...亚马逊公司创始人杰夫·贝佐斯宣布“21世纪将属于印度”，并宣布投资10亿美元帮助印度小企业跟踪库存、销售和账目；C项：The next day, Walmart Inc. said it would spend $1.2 billion on its Indian subsidiary, Flipkart, which faces growing competition from Amazon and, yes, Jio.沃尔玛（Walmart inc .）宣布将斥资12亿美元收购其印度子公司Flipkart。因此可知，只有微软没有投资印度。故本题正确答案选D。
