Here "A pain" is wrong I think.

Here there are two statements in the sentence.

1. He is not coming tomorrow as he is having a pain in the chest.
And
2. He has to see a doctor.

Here "And" is used as a connector so,
After and he must be there to start the second statement.
And we used he 3 times that's not a matter.
Because;
1.he- is used as the pronoun to represent a person.
2.he - is used as a reasonal helping pronoun for as.
3.he - is used to start second statement after connector AND.

Above two options are correct, But the error given by you is ambiguous. He is having a pain and he has to see the doctor. Here he is common between the two sentences. Then is not correct to take it common. He is having a pain so he has to see the doctor could be correct.

Whats is wrong with (and has to see a doctor) without?

B should be the answer.

We know that antecedent and pronoun should be appropriate. It should not be ambiguous.

Here we are speaking about the third person in 1st and 2nd part of the sentence but in third part who needs to go to the doctor?Whether the speaker or third person. So third party is wrong.

@Vertika.

"a severe headache" uses 'severe' as a supporting word but in the case of using "a pain" we don't find any such supporting word so I think its the wrong usage here.

Option A would be wrong. "He's not coming tomorrow". Tomorrow is future tense and isn't coming is present continuous then how could we club both? It would be "He won't come/won't be coming tomorrow".

He is having pain in the chest should be correct.

According to me, the sentence has no error.
