D. this
解析：句意：李刚案成为了一个热门的话题，李天一案也是如此。“this”、“that”既可以作形容词，又可以作指示代词；而“it”只能作代词。one可用数词又可作代词。 it／one ／that三者均可用作代词, 指代前面提到的名词。一般说来, it指代同名同物; one与that则指代同名异物。如：I have lost my umbrella; I'm looking for it. （该句中it就是指前面的my umbrella）；I have lost my umbrella; I think I must buy one. （one在该句中表泛指, 因为my umbrella已经丢了）；The umbrella you bought is cheaper than that I bought. （替代词that在该句中特指“the umbrella I bought”, 以区别“the umbrella you bought”）另外，one为泛指, 相当于a／an＋名词; that为特指, 相当于the ＋名词; one只能代替可数名词单数, 代替可数名词复数时用ones; that既可以代替不可数名词也可以代替可数名词单数, 代替可数名词复数时用 those。 one既可代替事物, 也可代替人, that只能代替事物而不能代替人。有时可以用the one或the ones代替that或those。The one ／That on the table is mine. （该句中The one代替事物, 并且也可以用That）；He is the teacher, the one who is loved by the students. （该句中the one代替人, 不能用that）；He advised the farmers to choose the best seed-heads, the ones ／those that had the best color. （该句中the ones代替事物, 并且也可以用those）；one一般有前置修饰语, 有时也可有后置修饰语或不用修饰语。而 that不能有前置修饰语, 但可有后置修饰语。it可以替代句中的不定式或从句等, 充当形式主语或形式宾语。one与that均无此用法。it与that均可以替代上文全句的内容或部分内容, 而one ／ones则不可以。He has saved my life; I'll never forget it. （it代替第一分句）Tom is painting his house. I am told he does it every four years. （it代替前面分句的部分内容painting his house）Let's say we meet here at three o'clock. That ought to give you time to buy everything. （That代替前面表述的内容）。由句意可知选C。
考点: 考查代词的用法。
