答案：
A. where do I come from
B. that my favourite subject is English
C. what did I like best
(答案→)D. if I could speak Italian
解析：句意：老师问我是否我能说意大利语。宾语从句的结构：主语+谓语+连接词+从句。从句在句中作宾语。从句要用陈述句的语序。如果主句是一般现在时，从句根据需要选择时态，如果主句是过去时态，从句要用相应的过去时态。但是从句是客观真理，一般用一般现在时态。AC选项是疑问句语序，故排除。B项，由于主句在问，从句应该是疑问的语气，故排除。主句是过去时态，从句应用过去时态。故选D
