_______________ the course of the development of different life-forms heredity

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2, i.e. In.

  • 'In' is correct because the word 'course' means the route or direction that's followed to achieve something or reach some place. For this instance, we can use 'in' because it denotes that something is highlighted within the course of development. The other options create too much emphasis, such as 'into' denoting that something is submerged inside something. The meanings of the other options portray a different sense from that of the given statement.
