The sentence indicates a change in habit from the past to the present.

• In the past his father *used to walk* establishes a past habit.

• *but nowadays...* signals a present habit that contrasts with the past.

• Nowadays typically uses the simple present or the present continuous tense to describe current habits or ongoing actions.

Let's evaluate the options:

• A. was going: This is past continuous, which doesn't fit with nowadays.

• B. is going: This is present continuous. It's often used with nowadays to describe a current, ongoing habit or trend. For example, Nowadays, people are using their phones more often. It fits perfectly here.

• C. seldomly goes: Seldomly is grammatically incorrect (should be seldom). Even if it were correct, seldom goes means he rarely goes, which contradicts the idea of it being his current way of getting to work.

• D. goes: This is simple present. While grammatically correct for a habit (He goes to work by bicycle every day), is going often sounds more natural with nowadays when emphasizing a *current practice* or a *change* from the past, especially when describing what he is doing these days.

Given the options, B. is going is the most natural and appropriate choice to describe the father's current habit in contrast to his past habit, using nowadays.

The complete sentence: In the past his father used to walk but nowadays is going to work by bicycle.

The final answer is D
