下面代码不能正确输出hello的选项为（）

#include<stdio.h>
struct str_t{
   long long len
   char data[32]
}
struct data1_t{
   long long len
   int data[2]
}
struct data2_t{
   long long len
   char *data[1]
}
struct data3_t{
   long long len
   void *data[]
}
int main(void)
{
   struct str_t str
   memset((void*)&str,0,sizeof(struct str_t))
   str.len=sizeof(struct str_t)-sizeof(int)
   snprintf(str.data,str.len,"hello")//VS下为_snprintf
   ____________________________________

   return 0
}

A. struct data3_t *pData = (struct data3_t*) &str printf("data:%s%s\n", str.data, (char*) (&(pData->data[0])))

B. struct data2_t *pData = (struct data2_t*) &str printf("data:%s%s\n", str.data, (char*) (pData->data[0]))

C. struct data1_t *pData = (struct data1_t*) &str printf("data:%s%s\n", str.data, (char*) (pData->data))

D. struct str_t *pData = (struct str_t*) &str printf("data:%s%s\n", str.data, (char*) (pData->data))
