woven fabric such as used in dressing, decorating, cleaning or other practical use
也就是“布料“的意思（而不是衣服,而且不可数名词）
clothes: 指具体的,看的见摸的着的衣服,比如 I buy some clothes this afternoon
再如： She has a lot of clothes in my bedroom
clothing: 指笼统的服装,概念的上衣服,
比如： One must wear protective clothing to enter the lab (必须穿防护服)
再如：We're collecting food and clothing for the poor. （为穷人募集吃的和穿的）
cloth比较好区分,就是布料衣料
clothes 和 clothing的话,好好体味这几个例句 -- 总的原则是,具体的一些衣服用clothes, 表服装这个种类或很泛的“穿的”这个概念用 clothing
注意原题的（those）说明是可数名词,符合题意的就只有clothes
