Final answer:
The pattern in the sequence involves moving the decimal point one place to the right, making the next number in the sequence 1.2 (option a).
Step-by-step explanation:
The sequence presented shows a consistent pattern where the decimal point is moved one place to the right with each successive number. Starting with the first number in the sequence, 0.0012, if we move the decimal point one place to the right, it becomes 0.012. Moving the decimal point one place to the right again makes it 0.12. Therefore, continuing the pattern by moving the decimal to the right by one more place, the next number in the sequence would be 1.2. Hence, the correct answer is a) 1.2.
