Hi, I think the answer is D, but I'm not entirely sure. An explanation would be appreciated, but I think it's because they're both not curly brackets.

What is a compiling error?

Which statement results in an Apex compiler error?

A. Maplmap = new Map([Select ID from Lead Limit 8]);

B. Date d1 = Date.Today(), d2 = Date.ValueOf(2018-01-01);

C. Integer a=5, b=6, c, d = 7;

D. List s = List{a,b,c);
